I liked what Washington did. They added a Hall of Fame coach and then went and upgraded at QB. They have some veteran RB's to add into the mix and they may not be done.
I think Washington will be a tough out this year, they played tough defense last year with Haynesworth in the game.
The Lions looked to have upgraded, Tampa Bay and S.F. However, not everything always translates to the field, so those teams to me will have to prove it, especially the Lions. One thing about Tampa and Detroit, they have 2nd year Qb's coming back so in that alone we should see improvement on turnovers and overall play.
Then you have Baltimore and the Jets, two of the better teams to go and upgrade. Unlike BostonFred, I like the Jets more. I would think that finally knocking off the New England Patriots has to be a huge target for them. One can argue that getting thru that tough division is a tougher task...and I agree that it is but that was also part of the reason they shined brightly in last season's playoffs. It's why Florida and Alabama shine in their post seasons. Battling thru the SEC doesn't hinder those teams, it makes them stronger in the end. I feel the same way about the Jets. If they can finally catch the Patriots, they could be the favorite to get through the AFC playoffs. To me, most of everything I'm talking about hinges on Sanchez, does he take a step forward or backward but the same can be said about Flacco. He's played a 2nd season and generally did OK, I think to win a SB he'll need to take another step forward hiself.
