Pats best at inducing dropped passes

Drops in the NFL have become a household statistic. With all the offseason chatter regarding Braylon Edwards and his propensity to put the ball on the ground, the effects of his drops on the Browns' offense are pretty obvious, but how do they impact opposing defenses?

A dropped pass for the defense is basically a gift from the offense, taking a play that would've otherwise been a first down -- or worse -- and turning it into a defensive stop. A key third-down drop could turn a possession that might've resulted in a touchdown into zero points and a change of possession.

We know that Edwards is prone to dropping passes, but are there defenders or teams who consistently cause the opposition to drop passes? Do intimidating safeties like Ed Reed or Troy Polamalu and shutdown corners like Nnamdi Asomugha and Antoine Winfield cause more drops than mediocre defensive backs?
