There certainly is frustration. As a coach I want my team to play better and I know I'm responsible for that. But until that question poses itself, I'm going to say my party line: It's not about me, it's about our team and trying to win games.
If certain guys step forward and assert themselves I think you'll see a more steady rotation but until that happens I'm going to keep trying to find who's playing well on a given night and who's got there head in the right place.
