I had a feeling that you may see it that way
Out of curiosity, with the obvious understanding that the games are not won/lost in the month of March, do you believe that ANY other AFC team has made improvements?
I see you've now pooh-poohed the moves of Indy, Miami, Buffalo, the NYJ, and are always generally down on Denver. That isn't even bringing Baltimore into the equation, as you were of the most outspoken people 2 yrs ago about their "demise." Do you feel that there is any realistic competition for the N.England Patriots out there?
The Jets have improved the most, I think. Revis will do that for ya! I'm glad they have a new coaching staff, though, which usually takes a while to truly settle in.
The bills? I liked Alonso a lot. Shady's good, but I like Spiller, too. And Shady is way but overpaid. They took some high-risk moves, but it could pay off, and they didn't mortgage their future like the Jets did. I think Chandler is a big loss, but Harvin could pay off. Cassel is serviceable. So they got better.
Miami is the wild card. Suh is a beast - I put him up there with Campbell. Truly elite. But that's a lot of guaranteed $$$$, they lost Odrick and Starks, Ellerbe, Gibson, Hartline...and now, apparently Wallace. Not a big Wallace fan, but he's better than Stills. Cameron, I'm not sure. Don't know how much "better" the Phins will be, honestly.
If Revis or Suh declines/gets hurt, those two franchise carry the suck forward for a long time.
AFC East really looks good though, so yeah, I think all three are improved on paper, here in March.
My money stays on the Pats. Furthermore, because of the moves they're making and the way they're doing them, the Pats look to be in good cap shape going forward, next year, the year after, etc.
