What produces a dynamic pass rush, if not pass rushers? Magic beans? Special cleats?
In the dynasty years, the Pats had Vrabel, McGinest, and Colvin, all of whom could be depended on to create pressure on the quarterback.
This edition of the Patriots has zero linebackers that can depended on to get to the quarterback. You seem to have the idea that the Super Bowl-winning teams had mediocre outside linebackers, but since they had a bunch of them, they could produce a pass rush. Wrong, they had 3 borderline elite pass rushers. Colvin was a fairly one-dimensional pass rusher. Belichick signed him to a fairly expensive contract. Obviously he felt it was an important piece to the defense.
You're lack of basic understanding is outdone only by your rudeness.
Vrabel had four years experience as sub-rusher in the Steelers 3-4. McGinest had been with the Pats for a few years before BB even came on board. Colvin was a veteran talent. All of them were proven as pass-rushers and Vrabel and McGinest had already demonstrated they could do some other things as well.
None of these guys were unproven rookies or cost BB a draft pick, much less a 1st-rounder.
