Everyone has been focusing on Bradford and the improved performance of the DL. Two things that I think have been crucial as well:

1. Bartell and Fletcher are playing lights out on the corners.
2. Saffold has been super solid at LT.

Saffold has out-performed three of the four offensive tackles taken in the first round. He is probably better than all four. Not sure about how Bulaga is doing with the Packers.
