With his position he shouldn't be worried about how many sacks he gets, his job is to stop the run and free up linebackers, which is why Ray Lewis lasted so long in the NFL because of guys like Sirgusa, Kelly Gregg, Sam Adams and Ngata, these guys were big and strong, Ngata was a freak of nature being he was big, strong and athletic. Hopefully Jernigan understands that, especially dropping weight the way he did. He's a 5 technique defensive end so his only job is to control gaps to keep offensive lineman from getting to the second level. So with him losing weight I hope he's gotten stronger and a lot more physical because if not he's going to have a long season ahead of him especially in the tough and rugged AFC North and make it hard from the linebacking core.
