Sal's article on WGR gives a very good explanation of the scheme: http://www.wgr550.com/two-bills-drive/19508975
But this is what really scares me:
It’s also why the Bills so desperately need Marcell Dareus to stay on the field and play at a Pro Bowl level. In many defensive schemes, there are more players committed to helping each other flush out the ball carrier. Not so much this one. This scheme relies heavily on those middle-of-the-defense defenders to make plays in space and often by themselves. If one gets beaten, huge chunks of yardage are at risk.
Two thoughts: 1) Anything that is dependent upon Marcell Dareus right now is a total crap shoot. And 2) Yes, we added Spikes, but our interior run defense has been very porous for the last few seasons, and it appears to me this strategy feeds into our greatest weakness.
Moreover, I have never liked the idea of spreading the lineman so wide, remember a few years ago the Eagles scrapped this system in mid-season because they couldn't stop the run.
Our weakness has been run defense, and this system makes any team more vulnerable to getting run over.
Well, I hope I'm TOTALLY wrong, but I just have a bad feeling. Any help ???
