    Q1's final drive spilled over into the beginning of Q2 and culminated in a Gonzales field goal to narrow the score to 17-10 Arizona. In the last three drives, the CU offensive platoon had racked up almost 200 yards and 10 points. However, from here foward is where the offensive unit would hit their first major slump of the game. The next three series, the CU offense would manage nary a first down and only 11 total yards.

    Quarter 2 Possession 5

    Series: 1 Play: 1
    Down: 1 Distance: 10
    Formation: Shotgun Personnel: 12

    CU aligns with a 12 personnel grouping out of the shotgun formation. Notably Carr is in at RB with Huckins and Kough at guards. The play is a simple inside zone. The failure here occurs when Nembot advances off of the combo block up to the second level, which leaves Irwin to fend for himself against the DE. The Zona DE makes a nice play here and slides off if the block to the inside. Irwin looses his position and falls to the ground. The DE wraps up Carr and reinforcements rally to finish the job.

    Elsewhere on the OL, Kough pancakes his man, Huckins and Kronshage root their assignment from his position and Kelley doesn't get a great push but neutralizes the NT. This play was never going to go for major yardage but if Irwin had been a little better perhaps this would have put CU in front of the chains.

    Series: 1 Play: 2
    Down: 2 Distance: 8
    Formation: Shotgun Personnel: 11

    CU aligns with an 11 personnel grouping, swapping Frazier for MacIntyre who now fills the slot to the field side of the play. The call is a run that may appear to be designed to go to the B-gap. Notice how Kelley seals the NT while Huckins and Kronshage drives their men outside. This creates a crease. Carr does not like what he sees in the initial hole and tries to bounce it wide and then wider. This completely negates the blocks by the OL to that side of the line. MacIntyre who is also a neophyte blocker at WR is again easily discarded as the defender pursues upfield forcing Carr back inside.

    It looks like Carr just elected to try to use his speed to get to the outside instead of picking up the tough yardage inside. This is a bad habit many super fast RBs have coming out of high school. Often in HS they can usually outrun the defense to the outside on almost any given play. He'll need to learn to break this habit. I could be totally wrong on that analysis, but judging how the play appears to be blocked, this is my guess.

    With that said, this is just unwise play selection with the personnel group. Kronshage is not a great run blocker and MacIntyre is not even a pylon at this point. Running to their side with an inexperienced RB seems like something with a long shot for any meaningful success.

    Series: 1 Play: 3
    Down: 3 Distance: 12
    Formation: Shotgun Personnel: 10

    It's 3rd and 12 and now CU is behind the chains. Lee has subbed in for Carr. He motions to the boundary side presnap. Zona again shows blitz but bails into coverage at the snap. The call is a speed option.

    Initially, CU appears to have a the numbers advantage but their is no space to adequately execute the play, especially for a team that doesn't run option. Kronshage and Huckins are both unable to get good blocks on anyone and the LB that showed blitz and bailed gets pushed off of Bobo's block by Kronshage, which frees the LB to make the tackle. It actually kind of looks like Bobo then hits Kronshage instead of the backer. Even if the backer had been sealed to the inside, there were other tacklers in position to stop the play.

    The play is an immense failure. I wonder if this option package by shown on the reverse and now this was the doing of BL or the offensive consultant brought in last week to jump start the offense. I don't ever recall BL running this before. This is one of the worse play calls thus far.

    Conclusion

    Going to go out on a limb here but perhaps one the biggest problems with the offense is that we are trying to use too many personnel groups. The core guys just cannot find a rhythm together. This goes for the OL, the RBs, and the WRs. Maybe we really need to shorten the bench like basketball or hockey teams do in crunch time. This may draw criticism but after another abysmal blocking effort by Jay MacIntyre on this drive, there is no reasonable justification why he continues to play ahead of guys like Lee Walker or Bryce Bobo, who have both shown to be effective and willing run blockers. Lee Walker is one of our best athletes and is exactly the sort of athlete we need to get the ball to more often. Bobo has already proven he is a capable WR 3 if given the opportunity. Carr has had a few explosive plays this year but other times appears totally out of sync with the offense. He does need touches but down 10-17 at the start of the Q2 with a sputtering offense is not the time to try to break him in.

    Quarter 2 Possession 6

    No gif here but Fields fumbles on the first play of the drive. Just a mistake by a young guy trying to make a play. The Arizona DB doesn't even look like tries to go for the strip, just kind of hits the ball. CU's defense makes a huge stop and Zona misses the FG on fourth down.

    Quarter 2 Possession 7

    Series: 1 Play: 1
    Down: 1 Distance: 10
    Formation: Single back Personnel: 12

    CU returns to the single back 12 personnel grouping set up for possession seven. Play call here is not too different as to many of the early drives started, with a come back route to Spruce on the sidelines. The thought process here is just to get ahead of the sticks on first down.

    Unfortunately, on this play it appears that both Irwin and Kronshage surrender pressure too quickly, though Zona does bring two extra rushers. This affects Liufau who may have wanted to throw to his right as his first read. Instead almost truncates his drop, wheels around toward his left and rushes his throw to Spruce before he looks balanced to throw.

    This play encompasses the debate on the among the community: The OL doesn't great protection, Liufau also doesn't appropriately shift in the pocket and becomes flustered. The throw is then off the mark. The play call itself while simple doesn't have a quick check down for Liufau to get rid of the easily and safely.

    Series: 1 Play: 2
    Down: 2 Distance: 10
    Formation: Shotgun Personnel: 11

    After the incompletion on first down, CU elects to return to the pass on second down to get ahead of the sticks. This play features the 11 personnel grouping with Irwin in the slot. The amazing camera angle by Fox prohibits us from seeing the receiver all the way to the field side of the play.

    Zona again shows blitz at pre-snap with off man to man coverage on the outside. As Zona has demonstrated throughout the first half, they show blitz with five or six defenders but will only bring a one or two extra men. Here the MLB feints the rush and drops into an underneath zone / spy assignment. The outside back rushes but is dispatched of by Lindsay on a great block.

    Either by virtue of the pressure of the play before or his own volition, Liufau panics. It's not totally clear where are the defenders are on this play but we can surmise that their appears to be bracket coverage on Fields to the boundary side of the play at the top of the screen. Irwin appears to have slight separation from his man but it also could be because his defender sees Liufau scrambling around. It does appear as though there was some space to potentially throw Irwin open. Regardless, Liufau sifts around trying to escape otherwise great protection and eventually scrambles for a decent gain.

    As the above play, this again exhibits why there is a great debate centered around Liufau, the OL and BL. Liufau clearly does not trust his OL to handle the blitz and does not have the flexibility to hot route a player or check into a different play or protection. Note, this drive appears to be the first time all game the Arizona defensive postures appear to be affecting his psyche.

    By great fortune, the ensuing punt on the series above hits a Zona blocker in the back and is recovered by CU on the Arizona 24 yard line. A run to Lindsay and a throw to Spruce get the drive started on the right foot, not unlike what we had seen BL try to do previously. CU almost self destructs when Kelley and Liufau miscommunicate on the snap count. Bryce Bobo makes a stellar effort on second down to weave threw traffic to get into a third and manageable situation. CU punches it in on a QB Power over the right side. Here is a summary of the plays that lead to the touchdown:

    1-10 Ariz 24 Lindsay,Phillip rush for 6 yards to the ARIZ18
    2-4 Ariz 18 Liufau, Sefo pass complete to Spruce, Nelson for 10 yards to the ARIZ8, 1ST DOWN COLO P10
    1-G Ariz 08 Fumble by Liufau, Sefo, Liufau, Sefo rush for loss of 5 yards to the ARIZ13.
    2-G Ariz 13 Liufau, Sefo pass complete to Bobo, Bryce for 11 yards to the ARIZ2
    3-G Ariz 02 Liufau, Sefo rush for 2 yards to the ARIZ0, TOUCHDOWN, clock 02:26.

    The next post will analyze the Q3 offensive woes.

    Series: 1 Play: 3
    Down: 3 Distance: 3
    Formation: Shotgun Twins Personnel: 10

    Even though Play 2 looked like a disaster, Liufau was still athletic enough to make do and put CU in a manageable third down situation. CU aligns in 10 personnel grouping with twin receivers split to both sides of the formation. Zona shows man to man coverage and six rushers.

    Zona, perhaps guessing run, bring all the the defenders at the snap. The protection is solid on this play. Liufau stands tall in the pocket knowing it's a quick throw here. He doesn't have to trust the protection for a longer period of time. The defense also reads exactly as it appeared before the snap.

    The call here is a good one, but CU falls down in the execution. Zona actually ran a ton of route combinations like this all night against us. Basically, Ross motions inside and switches the coverage assignments. He then runs his route off of the back of Fields giving him some immediate separation and causing the defenders to have to communicate on which receivers they will cover. In this case, Zona stays with the presnap assignments. The design of the play works however Ross stumbles on Fields foot coming out of his break. It doesn't look like Liufau double clutches his throw but probably safe to assume that perhaps he tried to reign his throw back in, not knowing if Ross was going to fall down or not. Hard to totally fault Liufau on the throw but it's still another failed third down conversion.

    Conclusion

    As we can see by now, CU is not as effective as an offensive unit if they are not managing down and distance. This may contribute BL's inability to open up the offense and call aggressive plays. It also makes the offense more predictable, which appears to be a frustration of many. It's paramount that CU have a positive play on first down and when that doesn't happen, frequently the possession unravels. That puts the offense in a precarious situation because then the first down call and execution needs to be flawless much of the time.

    Thought he was a generous with Sefo on that bad, bad, BAD miss on 3d down where he hopped it. The speed option stuff was handled abysmally. They ran it in the first quarter, and it totally shocked the D. But instead of starting with the speed option, they faked the speed and did a reverse on the first play. Since the D wasn't over compensating or looking for it, the reverse failed. You don't do the trick unless you see them biting hard on the standard play. Basic offense. Then you run the actual speed option to the SHORT SIDE. I'm a Lindgren fan, but he didn't handle that well at all.

    His point about switching up the personnel is well taken. however, this week I think we can expect a lot more of Jmac with Fields out. I don't mind Jmac in obvious passing situations, but until he can block, he has to be a spot player. I hope we see a LOT of Ross, Bobo, and Spruce.

    this is good stuff, as always.

    when your opponent has better athletes across the board, you better execute. sigh.

    That's why OSU is so big. First time since Nicholls we won't be out athleted at 75% or more of the positions.
