Yes, Frank micro-manages. Some players have an easier time with that than others--just like some employees do better with a micromanaging boss than others. To be fair, though, there were a dozen reports indicating that Frank worked with McInnis one-on-one for a long time trying to help him "get" it--but it never worked. And there were the rumours of why McInnis was REALLY asked to stay away (it had nothing to do with his on-court play).
What bugs me--and should bug everyone, but you NEVER hear about it--is that there are indications that the front office and coaching staff do not make personnel decisions together. Thorn will sign someone and say "it is up to the Coach to decide how to use this guy." If a player won't fit with the coach's system, why are you acquiring him? Shouldn't they first try to figure out who is likely to fit in and be successful before they go out and pursue someone? One reason why the Oakland As is successful is that Billy Beane both makes the personnel decisions AND decides how the players will be used. Why sign Magloire when there was approximately a zero percent chance that Frank would play him? I could go on and on. It seems like Thorn looks as players solely as assets--not puzzle pieces that have to ultimately interlock the right way.
