"Peterman looked good in Thursday's game. He shows some of the quick decision-making in the pocket that Taylor lacks. But he's a rookie. He's been facing mostly backups. He was average in the first two games. He hasn't completed a significant throw down the field.
Why wouldn't he start right now? Because it's Taylor job, assuming he's out of concussion protocol for the Jets game. I don't think Tyrod is a franchise QB.
I like what i've seen from Peterman thus far, but he's just not ready to lead this team at this point.
If TT goes down during the season, then yeah, throw the kid in for some licks.
