I had higher hopes for Trey Sanders this year, but with Najee playing so well and us passing so much, we don't get to him often.
I'm guessing he's not progressed well enough in his pass protection, or he'd see a little more time.
Some of these games have been closer than people have expected. I think, Bama goes with the hot hand/reliable hands of Harris. Both he and Robinson are game tested. Hopefully, they can work some of these guys in in the next few games.
