Yeah, although Jon doesn't play a particularly deep bench he's not a run his starters into the ground guy either, I think his bench minutes is pretty much in the middle as far as upper tier power conference teams go. And the idea that a player feeling no matter what he did he's not going to get minutes, just reeks of an inability to self assess objectively.
Jon Scheyer, or any coach, is going to play you if he felt you gave the team the best chance to win. Maybe you feel like you've worked hard and improved, but maybe you aren't seeing that the guy in front of you is also working hard and improved too?
