It has to be our offensive line as a unit. Everybody still bitches about the defensive linemen, but has mostly stopped bitching about the offensive one. Therefore, they are overrated. They are highly subject to the bitch, but seem to be mostly escaping the deep scrutiny and disdain they so richly deserve.
Gimme a decent offensive line and I will insert (select your favorite running back on this team) him through the hole created, and he will get through it just fine, thank you very f#cking much. Put this suck-#ss line out there, insert anyone of the 3 RB's in question, and generate a debate on which RB is over-rated.
Same with pass-blocking, or should I say, the lack thereof.
