A general manager doesn’t put his job on the line by selecting a quarterback at #1 overall unless he’s certain the player is capable of greatness. If Ryan Poles wasn’t sure about Caleb Williams, he would’ve either kept Justin Fields or picked somebody else. The Chicago Bears GM spent months evaluating the USC quarterback. Every single snap he took was analyzed. Teammates, coaches, friends, and family members were all spoken to. Poles did everything he could to get a picture of the player and person Williams is.
