Perhaps I'm 'misremembering', but wasn't it reported by reputable sources early in the '24 offseason that Tomlin has notably admired Fields since he entered the League, and has always desired to work with him?
Also, wasn't the timeline involving the acquisition of Fields/Wilson along the lines of:
1. Steelers heavily pursuing Fields; pursuit going nowhere.
2. Needing to do something, with time to prep for '24 Season running out, they sign cheap Wilson as a short term solution, so they at least have someone mannng the pivot in '24.
3. Unexpectedly, talks with Bears heat up again; Steelers acquire original target, Fields.
IMHO, Wilson has always been the consolation prize. It just worked out that the Steelers got their man late in the game, after they'd already signed off on a short-term contingency plan.
I think Wilson is washed, a relative shell of his former self, and the Player he is now is going to be in peril trying to run an offense behind that O-Line.
Fields is certainly an experiment, presently in the crucible, outcome yet to be determined, but one the Steelers would love to work out the way they've envisioned, given his age and skill set.
I also think the Steelers top brass' primary focus for '24 has much more to do with seeing if Fields is capable of living up to his potential, and being a long term answer at QB for them.
Any success that might come along with that, this year, is just icing on the cake.
To borrow a familiar OG Shark Pool phrase: this is all a ploy to motivate...Justin Fields.
