A quote printed out of context by a media outlet, not at all surprising.

This article shows that the line was a part of a larger praise for Bell and his work ethic/ability. He states that often JUCO players need a half season to transition, and that he had earned lots of time in the rotation. He says that the 80 percent mark for Ozigbo against Purdue was "unusual" and that all three guys would likely get a good number of snaps.
Greg Bell decided his talent was being under-utilized because he didn't get many snaps in ONE game, and didn't have the patience to give it more of a go over the next few to see how many snaps he would get. I see no signs of bullying or abuse in that quote.
I see a kid making an impatient decision on limited evidence.
