I thought Grimes did a good job mostly.
I would have agreed 100% until I saw the strides our OL made this year. He may have been the victim of a dumpster fire of an offensive philosophy battle between Chiz and Loeffler, but our OL was teh suckage last year. The same group (mostly) was good, and occasionally dominant this year. Hard to say exactly who was at fault for last season with regards to the OL, but some blame has to go to Jeff Grimes. As if that really matters now though.
