There's been some suggestions that switch to a 3-4 would be good.  I think there are some big problems with that, but I'm an armchair football player, so I thought I'd put it in a FanPost for discussion.  Obviously the biggest problem is the personnel.  As I see it, the biggest need for a successful 3-4 is what Gregg Easterbrook calls a Ticonderoga-class Nose Tackle.  Guys like Ted Washington, who eat up two offensive lineman on every play.  There are so few guys like that in the league, I think that's one of the reasons not a lot of teams play it.

I'm not sure what I would call this scale (size or quickness) but I would order these positions like this:  3-4 OLB, 4-3 DE, 3-4 DE, 4-3 DT.  The positions just don't line up.  Kiwi is probably the one guy who could be a 3-4 OLB, and maybe Tuck could be a 3-4 DE, based on his play inside last year.  A DE in a 3-4 plays more like a tackle and eats up lineman so the LBs can make the plays.  The biggest reasons the giants have gone away from the 3-4 in the last decade is because MIchael Strahan was at least one of the three best 4-3 Defensive Ends of All-Time.

At LB, we can barely field 3 LB's right now, so I don't see how we could field 4.  I think I saw an interview with Accorsi (maybe), where he said one of the biggest reasons for not implementing the 3-4 is the cap.  LB's cost more then lineman.  That's why the Steelers have to turnover their LBs so frequently.  With the money we're going to tie up in Eli and Jacobs, I can't imagine being able to afford a 3-4 for more then a couple of years. 

Thoughts?
