You may be very correct in that Marinelli may not want Poe, but I have to disagree with the value.
Poe is very big and very quick for his size. Poe DEMANDS a double team and even FredBeard had issues with him.
Poe would make a huge impact on the defense IMO, because he would DEMAND that double team allowing for the Collins, Crawfords and DE's to be singled and still get a push so the QB can't step up in the pocket.
When NE had the great defense -- who anchored the line for them? Vince Wilfolk -- a huge, quick 400lb beast.
I guess I will just agree to disagree with Marinelli and some others here. I still think you build the lines first and start with the middle. I still think a dominating 1T will be the key to a dominating defense even if he doesn't have the sack numbers, he just allows for the other DL to get the sacks by tying up multiple blockers.
I have seen it done several ways over the years with quickness and with power. In the end, it doesn't seem to matter which you utilize as long as the guy can dominate. Size does seem to help when everyone is tired though.
