Hypothetically, if Peterman got us a late TD and also led us to the victory in OT, I don't think the coaches have much of a choice. Peterman would start against New England. Maybe they use concussion protocol as an excuse (although that hit absolutely looked like a multi-week injury), but if Taylor couldn't get us 7 all game and Peterman gets us 10-13 in less than a quarter's worth of play against a top defense in the playoffs, I bet Dennison would feel so vindicated and would tell coach he has to ride the hot hand in Nasty Nate.
That being said, did anyone really think he was gonna get it done?
