I don't agree that he hasn't addressed it, things just haven't worked out to plan. Before this season, nobody would have guessed that our OL of Flozell, Allen, Johnson/Gurode, Rivera, and the rapidly improving Jacob Rogers would end up being as bad as it is now. Our centers and Rivera have been average, Rogers and Flozell are hurt, and suddenly our OL is crap again. It sucks, but you can't say the issue wasn't addressed. If they stayed healthy, things would be very different for us right now.
Vinny never had a chance, but Bledsoe has proven to be a stud when the OL holds up. Again, you can't really say they haven't tried to shore that area up.
