There are three possibilities with Justin Fields. 1. The Bears overrated him in their evaluations. 2. He’s not ready for the NFL. 3. The Bears are falling to sufficiently support him. A combination of at least two of the possibilities is undeniable.

The story said we didn’t learn much about Fields, other than he’s not able to overcome disaster all around him and that the Bears aren't a good team. Fields is dealing with a hand injury but the story pointed out the bigger concern is Fields state of mind at this point. Based on all of this, it's entirely possible the team does go back to Dalton when he's healthy.
