I'm a big Travis fan, but I CANNOT overlook the effect of having Willis in there has had on sacks.  I mean it was like night and day once Willis became the starter.  And I don't know how Travis compared WRT runs for 0 or negative yards, so it might have been a better run-blocking O-line than what we've seen this year, and Travis didn't exactly have much success before Willis became the starter.  His best game stat-wise was the 1st NE game, but it was a disaster in other areas for him.
