David Ubben Signing day is exactly a week from today, and it's time to take a look at who needs what in its 2011 class. Some schools have addressed these with their current class. Some haven't. Others are still trying. We'll kick things off with the artists formerly known as the Big 12 North and examine the South later today. COLORADO Cornerback: Jalil Brown and Jimmy Smith were pretty reliable for the Buffaloes, but both are headed to the NFL, and the Buffaloes could definitely use some depth behind their first-year starters. It's not quite as pressing of an issue considering their move to the less pass-happy Pac-12, but they still like to sling it out west. Receiver: Colorado isn't exactly starving anywhere on offense, but receiver sticks out a bit. Toney Clemons was good, but maybe not quite what the Buffaloes hoped he'd be in 2010, but they caught a break in getting Paul Richardson back after a great freshman season. The Buffaloes need some complementary pieces around Clemons and Richardson to replace departed pass-catchers Scotty McKnight and Travon Patterson. Next year, that should be tight end Ryan Deehan and receiver Will Jefferson. IOWA STATE Receiver: It's been a struggle for Iowa State in recent years, but they have to get better outside to help out their quarterback. Sedrick Johnson's transfer only worsens the Cyclones depth at the position, but Jake Williams and tight end Collin Franklin, the team's leading receiver, are gone. Shontrelle Johnson looks ready to become a big factor in the offense, but the Cyclones filling the space at receiver will make it easier for Johnson to replace running back Alexander Robinson. Safety: Both starters, David Sims and Zac Sandvig, are gone. So is the Cyclones top reserve at the position, Michael O'Connell. Sims was a top-notch talent that will be tough to replace, but Iowa State needs more depth here. They should be solid at corner with Leonard Johnson, Ter'ran Benton, Jeremy Reeves and Anthony Young, which could make the new safeties' jobs easier. KANSAS Defensive line: KU is losing three of four starters on the line, including the team's only All-Big 12 talent, defensive end Jake Laptad. Turner Gill wants more speed, and this is a place to install it. Tackles that tip the scales at 320 pounds aren't too necessary in this league, but speed on the edge can go a long way in stopping the pass. Quarterback: Neither Jordan Webb or Quinn Mecham look like long-term answers at quarterback for the Jayhawks. Mecham will be a senior, and Webb might develop into a better player as a sophomore next year, but Kansas needs other options. The Jayhawks hope Brock Berglund, the top-rated recruit in Colorado, is the solution to the problem. KANSAS STATE Running back: I hear your cries for Bryce Brown, Wildcats fans, but K-State can't expect to hitch their wagon to the former blue-chip recruit turned Tennessee transfer in the same way it did for Daniel Thomas. Thomas and his backup, William Powell, are gone, and the Wildcats need some depth at running back to show up. Interior offensive linemen: K-State loses both guards and its center from an offense that produced the Big 12's leading rusher in 2010. Don't expect them to do it again in 2011 without Wade Weibert, Kenneth Mayfield and Zach Kendall, as well as Thomas and Powell, but finding some new talent behind them will help them come close. Cornerback: David Garrett emerged as a budding star in 2010 ready for a breakout senior year in 2011, but the Wildcats lose Terrance Sweeney and Stephen Harrison, as well as safety Troy Butler. Like we've mentioned earlier, good secondaries are a must for success in the Big 12, and K-State had one of the league's worst in 2010. MISSOURI Receiver: Missouri has some good ones ready to suit up in 2011, namely Wes Kemp, Jerrell Jackson and T.J. Moe, but the Tigers don't have a true gamebreaker. They have some younger players in Marcus Lucas and Jimmie Hunt who they hope will develop into big-time, All-American caliber receivers, a la Jeremy Maclin and Danario Alexander. In Missouri's system, though, adding a few receivers is always a good idea. They certainly don't need any more running backs. Defensive backs: Mizzou doesn't have any huge holes that need to be filled with recruiting, but the Tigers lose both corners, Carl Gettis and Kevin Rutland from their 2010 team. Kip Edwards and E.J. Gaines look likely to fill those roles, but the Tigers could use some depth and keep recruiting in the secondary to help add some talent around Tavon Bolden and Matt White, safeties who will replace departed Jarrell Harrison, who actually had to play some linebacker in 2010 because of injuries. NEBRASKA Every kind of kicker: Alex Henery, the team's punter and kicker is gone. So is kickoff specialist and lover/producer of touchbacks, Adi Kunalic. Fan favorite Henery was hardly underappreciated by the Nebraska faithful, but they'll miss him even more if the Huskers can't find a suitable placekicker and punter. Bo Pelini was reportedly after Wake Forest commit Mauro Bondi this week. Receiver: Niles Paul and Mike McNeill are gone. The Huskers need Brandon Kinnie to come through with another good year and it'd be nice if Quincy Enunwa broke through in 2011, but Taylor Martinez needs some more help at wide out, and a couple new recruits could provide it as Martinez's passing prowess matures.
