Lamarr Woodley, 265 lbs. on a 6'2" frame. DeMarcus Ware, 262 lbs. on a 6'4" frame. James Harrison, 242 lbs. on a 6'0" frame. Clay Matthews, 255 lbs. on a 6'3" frame. Tamba Hali, 275 lbs. on a 6'3" frame.
All of these men are top pass rushers in the NFL as 3-4 OLB's and none of them led the NFL in sacks last season. Who led the NFL in sacks you ask? Look no further than Elvis Dumervil, 248 lbs. on a 5'11" frame. That's right, 5'11"! The man is a very underrated DE in the 4-3 but when Denver went through not only a coaching change but also a defensive scheme change to a 3-4 defense, Dumervil excelled and he never looked back as he owned the NFL by a storm with 17 sacks!
Dumervil's size won't scare anyone but what does scare opposing offensive tackles is Dumervil's speed. Marcus McNeil gave up 2 sacks against Dumervil in the first game of the Broncos and Chargers match-up. Joe Thomas gave up 1 sack against Dumervil. Flozell Adams gave up 2 sacks against Dumervil also.
He's a scary player as he's one of the best weak side pass rushers from the OLB position in the league.
