Yeah I took these comments as vague as they are to mean Fields is gone. It makes so little sense to keep Fields.
1. You have 3 years of games, and he isn't going to ever be an elite QB
2. The rookie deal is up after this season, with Willams or whomever it resets.
3. If Poles passes on a QB like Williams and he turns into an elite QB, Poles will be out of work in short order. If Willams busts the downside isn't as bad for his career.
