Okay, I read the OP and the first page. Here's what I think:
I think the average sports fan is so impatient for immediate results he doesn't see what is trying working for the best of the best teams in sports. Consistency.
Consistency in coaching. Consistency in management. Consistency in drafting. Consistency in how the team is run.
Belichick and the Pats. Coughlin and the Giants.
Torre and the Yankees. Francona and the Sox.
Jackson and LA. Riley and Miami. Doc and Danny and Boston.
Running things the same way works. Making constant changes to your lineups, to your locker room hierarchy, to the way you play offense and defense, to the way you treat players, to the way you do just about anything is bad for players at this level of performance.
It works in high school. It works some in college. But at the highest levels of competition and talent it is best to have a system, have a lineup, have a way of going about business and sticking to it through thick and thin, bad and good.
The Celtics players don't want to come in and not know their role or what is expected out of them or how and when they will play. They want, need and crave consistency for proper physical and mental preparation.
Hate Doc because he makes young players earn their keep and because he doesn't tinker with lineups or substitution patterns all the time. So what!!! I say its what makes him one of the best coaches in all of basketball. And if you don't think so, just watch. My guess is after his gig with the C's ends he is asked to coach Team USA someday.
