Here's my list:
Solidify the OL (probably a small vet signing or two while Dante's School of Dancing Bears gets back to business) and cut Cannon.
Extend Hightower, Collins, possibly Butler. Maybe throw Sheard in there as well.
Resign Hicks, dude was a beast.
Splash FA/trade moveS at WR. (Maybe Mario Williams comes at a reasonable price and we try to move Jones? Jimmy Grapes?). Restructure ot flat out cut DA depending on said moves.
Double dip at RB in the draft, haven't looked at many possibilities, Taylor's kid maybe? What little I've watched, he seems to have ridiculous lateral mobility, think I read he hasn't fumbled in his collegiate career...no extra gear when he's in space however.
Couple cheap FA signings at lb, of the "see what sticks to the wall variety."
