We were in the 3-4 last year, keep that in mind (although we played a lot of snaps at 4-3). We moved to a 4-3 this year. Last year, Shawne Merriman went out in the 3rd or 4th game with the Achilles injury, and Kyle Williams, our Pro Bowl NT, played with a bad foot for weeks before finally ending up on IR in week 6 or 7, somewhere around there. Once we lost those guys, it was down to Dareus alone to get push up the middle and Chris Kelsay (ugh) and Dwan Edwards (meh) to come off the edges. Our linebackers were also in and out with injuries, and they were an average group to begin with aside from Nick Barnett. Our D started bad and got significantly worse. Coming back (1) healthy and (2) in a 4-3 is going to change the way this D looks and feels for the better.
Also, I don't think anyone is going to LA. They can't support a fucking team there, and they've proven that multiple times in the past.
I see, even though you dropped several names i never heard of i kind of get it. I thought the Bills used the standard 4-3 which is why i was a little perplexed with such a huge DE signing when you said it was working early in the season. But even if you assume your front seven get to NFC East-level do you really think paying a defensive player that much is worth it? I mean, i understand Megatrons contract. He scores points after all. But giving a DE 100 million seems crazy to me. Do you know how much he will have to do to make that contract look appropriate? He better push them to top 3 sackiest teams... Also, i make a big deal about this contract and not LF/CJ/anyQB because offenses are easier to build and you need fewer players to have a good offense. So having a gigantic contract on them doesn't hurt the team as much. The defense is a different story and you really need a lot of quality guys(just look at the Vikings).
Also, the Raiders left because they had a crazy owner. Not our fault. Don't know(or care) why the Rams/Chargers left. LA is a huge bandwagon city and will only pay attention when a team is winning(which is why i expect riots when the Kings win even though nobody cared a few months ago). But should us loyal football fans be punished for the stupidity of the general population? I don't think so. And trust me, when a stadium gets approved and the ball gets rolling several teams will be more than tempted to move to this great(if way to shallow) city. Though if the Raiders move back, i'll stay a Giants fan for life or until they get a QB i like enough to obsess over.
