In a recent expose piece from NFL journalist Tyler Dunne, he reveals how the Chicago Bears used to have a "toxic" QB room, which included Justin Fields:
According to Dunne, back in 2021, Fields - along with backup QBs Nick Foles and Andy Dalton, all had a messy relationship, mainly involving Fields and Foles.
Dunne explains how Foles would attempt to mentor Fields and teach him some tricks, but Fields was not interested. The two reportedly "could not stand each other."
Dunne did not reveal his sources, but indicated that they were close to the Bears.
