Some background on these numbers: the Hokie offensive line was in a state of flux early in the season--their starting RT (Ed Wang) was hurt, so they played some players (but not Brown) out of position to cover. The line played terribly until Wang returned and everyone else went back to their regular spots. In particular, Glenn Dorsey ate the interior line alive when LSU mauled the Hokies early on--but he was not the only one: ECU and Ohio (University, not State) gave the Hokie offense fits.
To make matters worse, VT alternated between a human statute (Sean Glennon) and their requisite Michael Vick clone (true frosh Tyrod Taylor) at QB. Glennon settled down and played well as the season went on, but he has about zero pocket presence. As for Taylor, scrambling is about the only thing he could do consistently, and he ran himself into quite a few sacks.
Now, I don't have the numbers on how many sacks were attributable to Brown (I've seen someone post 8.5 here). Chris Long got him twice, but on one of them, Brown was clearly expecting help from his LG but none was coming.
Still, the Hokie OL and overall offense improved dramatically as the year went along. They backslid in the bowl loss to Kansas, but (file this tidbit away "for entertainment purposes") the Hokies are invariably a disappointing bowl team.
We have some work to do with Brown, but the kid as all the tools. If we can squeeze one more year out of Salaam, we may have LT solved for a long, long time.
