I read a lot more into the Oline problem than maybe I should. Blitzing isn't the thing I worry about with the line. Poor protection and lack of offensive efficiency against a team that blitzs a lot can be as much a problem with running backs as it is the line. At the scrimmage Saturday, the backs were just horrible at picking up blitzers; but guys, I'be got to say there are some massive athletes that are doing that blitzing right now for the Herd.
My concern for the Oline is that I saw no discernable difference in their effectiveness in run blocking. If you can run block, teams can't blitz that much on you. Run blitzs are very dangerous, once the RB is gone, there is a 15 to 20 yard gain right in front of them. So if you're ever going to slow down a blitizing team you do it with beating the crap our of their interior Dline, and running sets that take their LBs out of the play (again, RBs have to be good for Olines to be good).
I believe here are kids on our team who are going to be very good, and they may end up displacing the current veterans before the season starts if Devers and Dowery don't pick it up soon. But it won't be because they can't stop blitzers, it will be because they can't run block well enough to give the Offense the versitility it needs to be successful.
