Like has been mentioned, Wilson's hit is a very affordable 19M if traded. I think most are missing the point though, of adding a stud QB like Wilson/Watson. If you are going to trade multiple 1st round picks for a QB AND pay him tons of money, the whole point of doing that is that you think you're a QB away. If you get the QB at the expense of multiple starters (Hicks, Fuller, ARob), now you went from being a QB away to a DE, CB, and WR away. And since you traded multiple picks away, you won't be able to sufficiently replace them.
So, if the Bears feel like they are even close to Wilson or Watson, best believe they have plans to restructure contracts, keep everyone, and make a run in 2021.
