Bears defensive tackle Israel Idonije is rated the fourth-most productive pass rushing defensive tackle, according to the website Pro Football Focus.
The formula PFF developed doesn't necessarily determine best but rather the most effective, based on sacks, hits and pressures. Obviously, though, sacks got the highest value.
Among all defensive tackles and defensive ends in 3-4 schemes, Idonije was fourth, behind San Francisco's Justin Smith, Cleveland's Shaun Rogers and Tennessee's Tony Brown.
Dwight Freeney of the Indianapolis Colts was the highest-rated pass rusher, based on PFF's formula.
New Bears defensive end Julius Peppers was eighth among defensive ends, two spots above Minnesota's Jared Allen and three spots behind Minnesota's Ray Edwards.
