Define "very good." He was an adequate starter, but he didn't stand out. Nor was he dominant. A kid that size coming in with an offer from Miami, I was hoping for / expecting a bit more. And on a team in desperate need of impact OL, he was adequate, but not much more.
Please understand, I'm a Tiller fan. I have stated repeatedly on the forums that he has been our most consistent OL the past two years. But he didn't exactly tear it up [which can be both good in the sense that he wasn't making mistakes and bad because he wasn't standing out], either--hence, why I consider him average instead of "very good."
