ESPN: Belichick re-defining the linebacker position

This article is a definite must-read, but it’s back from September 2005 when the Patriots were coming off their 3rd Super Bowl in four years and everything was just rainbows and roses.

This is the best section…

Belichick’s 3-4 scheme is the next step in this evolution. The Steelers’ 3-4 zone blitz was defensive-line oriented and redefined what defensive linemen could do. The Patriots’ 3-4 scheme is linebacker-oriented and is similarly breaking the mold for linebackers.

Belichick recognized two problems with a defensive-line oriented zone blitz scheme. First, even though you can drop the nose tackle into the short zone, it’s not likely he’ll be agile enough at 300 or so pounds to be adept in coverage. Second, to run the scheme properly, a team must find very athletic defensive ends who not only can play the run and rush the passer but also can drop into coverage. Such players are rare.

The Patriots’ solution to the first problem was fairly simple. Instead of dropping oversized nose tackles into coverage, they opted to give that assignment to the 3-4 inside linebacker. Known as “pluggers,” these are bigger linebackers whose main purpose is to stuff the run, but they can defend the pass better than nose tackles. On passing downs, about the only time they’d need a nose tackle to drop into coverage, the Patriots replace the lineman with a plugger linebacker lined up as a nose tackle. If the opponent runs the ball, the plugger is big enough to help stop it. If the opponent passes, he’s much better equipped to drop back.

New England’s solution to the second problem was, in hindsight, fairly obvious, but it didn’t seem so at the time. In 1996, New England drafted defensive lineman Tedy Bruschi out of Arizona. At 250 pounds, Bruschi was a bit small to play defensive end and was struggling, so Belichick and his staff decided to teach Bruschi to play linebacker. His success as a rush linebacker in the 3-4 zone blitz scheme led to an epiphany of sorts. The Patriots realized they could draft undersized defensive linemen and convert them into linebackers. In doing so, they oriented their zone blitz scheme around linebackers rather than defensive linemen. This subtle and seemingly small change had several advantages.
