Fields definitely won't, but Wilson might be good enough for the Steelers to be top 10-15 in the league in scoring, if the running game performs as expected and Pickens and Freiermuth stay healthy.
Given Wilson's age, it's not like he would be signing for 5+ years on his next contract.
To me, if he performs reasonably well, he would definitely be worth bringing back for another year or two.
The Steelers would have to pay up, but 30+ million per year is where the market is for merely average QBs in today's NFL.
It will all depend on how Wilson performs, but it would be easy to scoff at paying him only before considering the alternatives. Fields ain't it.
