I've been consuming all the Coach K stuff I can the last few months. Books, interviews, etc. This is a bad habit of mine. I don't appreciate a guy until the very end of his career and then I circle back and try to catch up.
Anyway, in the second half of Coach K's career he had no schematic dogma. He had certain values he expected his players to adhere to. But every off-season, he would look at the roster, the film on incoming players, watch all the film of team and individual workouts, and meet with his assistants and devise the schemes for the anticipated roster. Holding JBB (or any coach) to the expectation of an all-time coach isn't fair really. but he isn't even trying to do this sort of thing. On defense it's schematic rigidity + effort. on offense, it's "Get Garland the Ball and GTFO of the way."
Coach K also talked about screaming at players. How it works in college because 1. they're not paid and HC is god and 2. by the time they want to tune you out, they're out of the program already. He also talked about how he changed his approach a lot when he went to work with Team USA (pros) and how each player required a different type of motivation. Barking platitudes about effort and rah rah stuff eventually falls on deaf ears. that's what I took away from it.
Coach JBB seems like a cool dude and the players seem to like and respect his get down. but he's clearly the "the guy before the guy." I don't see the traits. or even glimmers of traits seen in great coaches.
