It's by no means a done deal yet that Wallace is going somewhere else next season. If it does come down to that though, the Steelers will at least get a first round pick out of it. Is that a decent trade off in your opinion?
In the end if you can't afford Wallace then you'll be happy with whatever you can get but at least it would be a good draft pick.
I would still like to see him stay but man the last time the Steelers had 2 first round picks was in the 70's. Imagine how much you do with that now? 2 offensive lineman, 1 lineman on offense and one on defense, 1 lineman and 1 middle linebacker.
You could deal one of those picks for more 2nd round and 3rd rounders. Take both of your first rounders and move up if you really want to go after someone like Kalil or even Blackmon. Ok that's a bit of a stretch, lol. but you get the idea.
