Giants have made some huge moves, picking up a shut down corner in Sam Madison and the best OLB in the game in Lavaar. Also Sinorice Moss for the slot. The deadskins also made some impressive moves picking up Johnny Lynch, Brandon Lloyd and Randle-el. But the team with the best off season moves, I believe, may be the Saints, only because they improved in so many areas and so far on paper, could go from a no-contest to an team fighting to make the playoffs.
The cross-town team the Jets made some nice moves although they loss Abraham. They picked up Van Olhoffen from the Steelers and started to rebuild that O-line with Ferguson and the center from Ohio State Nick Mangold; they also got I think a pretty good QB Kellen Clemens from Oregon. I also like what the St.Louis Rams have done with the addittions of Will Witherspoon from Carolina, La'Rio Glover at DT, Corey Chavous and Tye Hill in the secondary; they needed help on D-fence!
