Of the Rams backup O-linemen, who's considered to be the best run blocker.
I know that Noteboom's pass blocking is considered better than his run, but I'm wondering if he's still better at it than the rest of the backups.
Essentially, I'm wondering if, WHEN McVay decides to go heavy with an extra lineman (presumably in rushing situations), he's bringing in his next best run blocker.
