Just a simple extrapolation (and yes, I know it's inherently flawed due to oversimplification), let's take Dobb's 13 sacks over six games and double it to reflect a 12-game regular season. That's 26 sacks. Add in an arbitrary few more due to projected bowl/CCG sacks given up.
Last year, the following teams took at least that many:
Clemson (10-3): 27 sacks allowed through 13 games.
South Carolina (they had a very good offense) (7-6): 27 through 13 games.
Boise State (12-2): 28 through 14 games.
Notre Dame (8-5): 28 through 13 games.
Ohio State (14-1): 28 through 15 games.
Kansas State (9-4): 30 through 13 games.
Oregon (13-2): 31 through 15 games.
West Virginia (7-6): 31 through 13 games.
Southern Cal (9-4): 32 through 13 games.
Arizona (10-4) and Arizona State (10-3) each allowed 40 sacks through 13 and 14 games respectively.
Point is, sacks don't tell the whole story on an OL:
2014 National Rakings: Total O/Rush O/Pass O/Scoring O
Clemson: 61/91/39/54
South Carolina: 35/67/21/42
Boise State: 14/31/24/9
Notre Dame: 34/70/19/40
Ohio State: 9/9/52/5
Kansas State: 50/104/17/23
Oregon: 3/22/10/4
West Virginia: 12/45/9/36
Southern Cal: 31/68/15/23
Arizona: 26/47/22/30
Arizona State: 36/58/33/16
Okay, I may have gotten carried away with the stats, and Clemson may be a bad example to include in the bunch, as they got a lot done by their defense last year. Kansas State was a very pass-oriented attack, as were Southern Cal, West Virginia, Notre Dame, and South Carolina.
I had a whole tin-foil case study regarding Butch's time under Rich Rod at WVU, and how Rich Rod's offense at Arizona was effective this year, and yadda yadda, but there are enough differences to throw things off and it's all blind obsession and very basic (flawed) statistical analysis anyway.
The whole purpose of this post is that even while allowing a lot of negative plays, an offense can be not only productive, but pretty darn potent.
