Coburn also a massive miss. Even if you have Lath in front of him as a starter, we miss him as an option of the bench and to help close games out. Lath only looks like he has 60-70 mins in him, playing with the intensity that we demand. I would personally rotate Coburn and Lath around a bit depending on the opposition's strengths. Keep them guessing. They pose two very different problems so if the opponent doesn't know which one is playing its difficult to have definite game plan.
It was between Smith and Coburn for the third spot for me.
