Who really knows how they are progressing, especially when you factor in they block a terrible DL everyday at practice. Any lineman can block when all they have to do is play patty cake with Potoa, Tani, Finau, Turpin, etc. How many above average DL do we have? 2, maybe 3 at most.
I stopped caring about what the practice reports say, because they often don't mean shit. In 2008, our OL was huge and overpowering everyday in practice. We all know how that turned out. Demetrious Bronson tore it up at spring ball in 2009, now he can't even average 4 ypc at Eastern. Last year, Mickens had a bunch of hype from killing it at practice, and went out and laid an egg basically all season (he will be good eventually). Last year, Sark actually said he thought he would have the best OL that he had had throughout his tenure. Like I said, these practice reports are shit.
