Kidd is the Defacto DAL GM

[Kammrath]

I don't see any issue with a head coach doing coach-y things, such as set lineups and decide rotations and dole out minutes in a way that fits the situation as he sees it. Where I would get concerned would be if he is NOT the one making such decisions.

I definitely agree. But there is a line crossed when a coach goes out of his way to NOT play or best utilize a player that he didn't want in the first place. RC did that a couple times. I believe Kidd is doing it with Wood. It is an attempt to basically strong-arm the GM into doing exactly what you (the coach) wants in regard to roster construction. 

A coach SHOULD have input in the roster construction, but he also needs to trust the talent evaluators and adjust his coaching to fit the talent he is given.
