Two things.

I don't think Gurley's low yardage runs can be blamed on inconsistency on his part. I think it was the patched up oline, and the staid, predictable offense.

While Havenstein definitely exceeded expectations, I don't think he was the only olinemen who did.
Jamon Brown and Cody Wichmann performed well for rookies taken in the 3rd and 6th round.
