Y'all know I'm not a big supporter of Isiah Thomas' coaching, but I really don't think Doc is much better than Zeke.
I may be in the minority on that point, but I think Doc would be better off staying on TV forever (he's pretty good although its hard to tell when he has to work with Al Michaels) or spending some time as somebody else's assistant before he's a head coach again.
Having a good relationship with the players is a very, very small part of the job that receives more attention than it deserves. Not that it isn't important, but this is 'coaching', so things like x's and o's, strategy, rotations, practice, gameplans, etc. are more important. It's more than just the ability to diagram a play, I can do that for crying out loud, but I don't claim to be 'coaching material'. Its evaluating your team's strengths and weaknesses, and the opponents strenghths and weaknesses, developing a scheme to beat them, and preparing the players to do it.
The hardest parts are the last two, and Doc hasn't shown me much of anything there.
