After half a season, the Panthers have allowed 18 sacks on the QB.
Jordan Gross has a whopping 7 (SEVEN) of those! Per this Fanhouse.com post, that ties for the league lead -- and he's giving them up quick, averaging, by their assessment, 2.6 seconds from the time the ball's snapped.
15 of the 18 the Panthers have allowed are directly attributable to offensive linemen (3 each to Otah and Wharton, only 1 each to Vincent and Kalil) -- so the other 3 lie either on Delhomme or an unidentified RB or TE who missed a block on a blitz.
It's not acceptable to be an All-Pro, get an All-Pro's paycheck, and be leading the league in such an infamous category as this -- especially when he's protecting the blindside, and the sacks he surrenders often lead to lost fumbles.
