they dont both play inside, at all. Chris was never an inside player. I love Jimmy B, and he is a great coach, but he is not always right. Most of the fan base can see that Chris can shoot and play away from the hoop. Make no mistake, if there was no injury... this lineup would be on the floor 70% of the time (G and Cooney up top). And with that being the case, I dont think so many of us would be praying the ban is this year. This team would be top 25 with that lineup. Easily.
Roberson simply had not earned the PT when Chris was healthy. He has gotten much better IMO.
