The base salary on Solder's contract really isn't bad at all this year, thanks to his restructure. The Pats could trade for him and only be on the hook for whatever prorated portion of $5.4m remains for this season, I believe (so about half of that?). Then, they could cut him after this season with no dead money I think, since all the guaranteed money would stick with the Giants when they traded him?
I may be off there, but if that's the case it's definitely not that much money and is totally doable. The issue I have then is that even a merely competent-ish LT has a lot of trade value, and the Giants could command a lot for him given that he has a totally reasonable contract post-trade with them eating all of the dead cap associated with his guarantees. I think it would take a lot to get him, but if Wynn doesn't look like he'll be able to come back it's the kind of move that could win us the SB without costing much on the cap, so I don't hate it.
