I would have to agree. One of my fears (and I am being overly paranoid here) is that the very thing that Smart is good at (which is being a player's coach, having very personal relationships with all his players) could end up being the team's downfall when those relationships get in the way of him being tight on his rotations. In a recent interview, he said something along the lines of (paraphrased) "I know players around the league like to know how many minutes they're getting a game and when they're playing, but I would like to have a team where we can have 10-12 guys playing".
There's no team in the NBA that is deep enough such that the 12th man gets regular minutes. None. Because if the team did there'd be issues of balance, too many players competing for shots and quality minutes (like we foresee with Brooks/IT/Thornton/Evans) resulting in unhappiness in the locker room. That's the way it works in the league. Would it be nice if everyone could get along and Kobe would play 15 minutes a night so that Devin Ebanks and Darius Morris get a chance to play every game? Sure! Would it be great if they could do that and still win? Sure! But it doesn't happen, and will never happen.
