It's small beer in the grand scheme of things, but if he plays the Steelers have given for Fields what they got for Pickett and imo got the better players doing so, although 1 less year on his rookie deal. The Bears have played their hand badly, the market for Fields was supposedly stronger earlier in the off season, but a combination of thinking they could get more / wanting to give the illusion that they weren't taking Williams has cost them a 2.
Mahomes wasn't a winning college QB more to it than that Alan as you know, Williams is supposed to be the best college QB coming out buzz wise since Lawrence, whose been OK, Burrow was the one before that whose been great when not injured. If they had their time again I bet they wish they'd traded Fields last year when they would have got more for him in what was seen as a weaker QB class and taken Stroud, but hindsight and all that.
