Bagent is going to stick in the league for a long time as a backup, but he’s not a “plan A” talent.
I agree. He's cut from the 'Game Manager' kind of cloth. But it's the way the team seems to respond to him on the field that catches the eye in contrast to Fields. I don't know if Fields simply remains unsure of himself out there or that he just lacks confidence... but there's something unsteady about how he approaches the position on the field and his teammates.
The fact that he played at 'TTHHHEEEE...' might have something to do with this. He had elite talent all around him so Fields didn't have to carry the burden all by himself. But on the Bears people see him as having to the 'The Guy' who needs to do way more... and he doesn't have the same number and level of elite talents around him. So in a sense, playing College Ball where he did may have gotten him used to something that wasn't going to last and he hasn't adapted.
