Numbers for linemen mean jack. I am a lineman, so I can explain to you why. Sacks wasn't even a statistical category until like 10-15 years ago if I'm correct. The line is the most commonly misunderstood aspect of football. As long as you have your man in position, and you control the gaps (when on defense), you are a successful lineman. If you beat the other lineman to the gap that you're assigned to, and you control your area, even if the play doesn't go to you, you still did a hell of a job. Watch Seymour control his area next time you're watching. No one does it better. He plugs the holes so the backs can't get through. That's why they're forced outside, and most commonly tackled for losses. Does Seymour get any credit for that? No. It's the most underappreciated and unrecognized thing, yet it's the most crucial when you're a lineman. You make plays without actually being a part of the tackle. I take Seymour over Freeney everyday. Peppers is just ridiculous. Best lineman in the NFL, IMO. I still watch when he chased down Vick and I'm amazed. Freeney's only useful for pass rush. That spin move is the worst thing a lineman can do. I don't understand why he's so successful with it, but when he is it works. The other half of the time, when it isn't, he'll find himself on his ass. When he spins he takes his concentration and bearings away from where the ball is.
When analyzing and comparing lineman, you honestly can't use numbers. Freeney might be getting sacks because his other fellow lineman created that opportunity for him. It's why football is the best example of a team game. It takes all 11 men on the field to do their jobs, or you're screwed. Plain and simple.
