Obviously, future events could warrant changes (and I'll try to do updates as available players change), and the money needed is still an unknown (although I tried to take it into account as best I could at this point), but here's a first stab at how to fix the offense, outside of the draft...
Matt Forte (FA) - RB
Chris Ivory/LGB (FA) - RB
Josh Gordon (Trade) - WR
Jermaine Gresham (FA) - TE
Jeff Allen (FA) - OG
Unless Gresham gets wildly overpaid, I think that group could be had (if at all) for reasonable money.
Holy crap Deus. If the Patriots were able to swing all that, and add young talent in the draft at OT, OG, WR, and RB, good grief this team would be loaded.
Depending on the price (and the price shouldn't be much), I'd absolutely take a flier on Josh Gordon. The guy has *immense* talent. Forte/Lewis/Ivory in the backfield would give the Pats three pretty sweet options. Gresham is better than Chandler. Allen would be very helpful to shore up the OL.
If this is what the Patriots did, I'd be deliriously happy.
Probably *none* of it will happen, of course.
