The dude is pretty much an undisputed defensive genius.Really? Those are the two characteristics I'd consider him worst at. He might succeed despite his flaws (other coaches have), but mentally he's pretty unstable. He reminds me of Woody Hayes, who's instability was his ultimate undoing.I still think he has the mind and fortitude to be a highly successful coach at the highest level.
And despite the claims of his anger problem, he knows how to draw effort out of kids. And that's the #2 most important aspect of coaching, just behind being a truly gifted offensive or defensive mind.
