Actually that's not true. Bo gets very animated going after the officials but he almost never gets up in the face of his players.There are probably exceptions but in general you never see him yelling at a player as he comes to the bench like you see Izzo and Crean or the other Bo (Pellini) doing all the time. In fact when a player makes a mistake, he gets pulled and sits on the bench and Bo rarely even says anything to him. They know what they did wrong. A good example is the first game with IA (I think it was this game). In the first minute or so Dekker went under a screen rather than fighting through it and Uthoff hit a jump shot behind the screen. Bo immediately got up and sent in Dukan for Dekker, who of course is one of the expected stars of the team. Turned out that there wasn't a time out for several minutes so the substitution didn't take place for a few minutes. Dekker went to the bench and I don't think Bo said a word to him, but one of the assistants probably did. Dekker then went on to play one of his best games. Just a very common example of the way Bo motivates players with playing time and not emotion.
