I have posted a number of times that while MacIntyre and staff seem to draw up great game plans, they don't seem able to make in-game adjustments to counter the counter-punches. Yesterday, I heard Barnett on the radio talking about this "halftime adjustments" topic. To paraphrase: 1. They almost never happen. 2. A big reason is that assistants may suggest something but no head coach will go with anything they didn't practice. He's got a new book coming out in which he addresses this topic. In my experience, the in-game focus is on finding where guys are not reading something correctly or the coaches are identifying opportunities where a certain offensive or defensive play call the team has worked on is set up and could deliver a big play. Coaches don't alter game plans during games. They focus on improving execution of the game plan. They focus on making the best play calls within that game plan. The rest is on the players, their level of execution, their will to win, and whether they've got the talent to pull it off.
