I still don't get this "players manager" BS. Players respect managers/coaches that actually stick to their ideals and do the intelligent thing, even if it is an uneasy decision. I know I'm probably going to get a ton of crap for using this example, but just look at Belichick. Sure, he probably does have some enemies, but his players have a TON of respect for him because he puts winning ahead of EVERYTHING. A benched player might not be happy for the decision, but they still respect the coach and stand behind him, realizing it was for the best of the team.
I look at coaching like a science, there's not that much gray, either is the right decision or it's the wrong decision. Letting emotions and friendships get in the way only leads to problems and mistakes.
