I actually thought Philly taking the FG was the bad percentage call:
Attempt TD:
Succeed: Philly leads by 9, game over
Fail: GB ball at own 1 down 2 with 25 seconds, need 65 yards just to attempt FG for win, not guaranteed
FG:
GB ball back down 5 with 25 seconds, need 70 yards for guaranteed win (if you take touchback)
