If you want to criticize him for the OT possession, that’s fine. He had Thompson for a TD on the first play and missed him and then it went downhill from there.
I don’t really feel that you can blame him for the two three and out’s, though, when you consider what those plays were.
Drive 1: Booth rush for 1 yard, sack, sack
Drive 2: Booth run for 4, pass to Thompson for 5 yards, KT run for no gain
What part of those two drives are on Shapen? Even if he avoids the sacks and throws it away, you’re still punting on the first drive.
