Last season, the Titans pass rush was one of the league's worst. However, it's shown some promise in the preseason, and if Sen'Derrick Marks ends up playing, then the Titans will at least sport a dangerous interior pass rush.
With the Patriots' offensive line in transition, the Titans have an opportunity to really make things difficult for Tom Brady.
Of course, the real question is how much the Titans pass rush has improved. Kamerion Wimbley is now on the team, but he won't make the difference by himself. The Titans need Akeem Ayers and Derrick Morgan to step up and contribute as well for a decent edge rush.
But collapsing the pocket from the interior might actually be better. First of all, the Titans are much stronger on the interior line than outside. Jurrell Casey looks to be just as good as last year, if not better, and Sen'Derrick Marks has dramatically improved from last season.
Then there's always Karl Klug, who led the team in sacks last season, and Mike Martin, a third-round pick from Michigan. It's a very good group.
Second, Brady likes to step up into the pocket when he throws the ball. If the pocket collapses, then he can't do that, and getting Brady out of his comfort zone on throws is exactly what the Titans have to do if they want to win.
