My best guess would be a Fields trade. Chicago probably wants Williams with that #1 pick.I bet they trade for a busted prospect. Howell probably impressed them, if they can get him for a day 3 pick it would make sense to have him compete with or backup Stidham. I don't think Fields makes sense although I could see conservative Payton wanting a running QB more than other teams.
Probably will draft a QB at some point but so many areas they need to shore up in the draft. The OL pool looks deep, really need a long term OT solution hopefully to replace McGlinchey in a year when his cut cost goes down.
Honestly wouldn't be a bad trade for like a 4th round pick. Fields has actually had an ok year with signs of improvement.
