He(coach) wasn't on the field...the players need to make plays and the D just could do it.
Josh did his part killing 6 minutes on the first of 2 TD drives and 50 seconds later the Bills were trailing again.
Then Josh gets them the lead again leaving 13 seconds...again they can't cover and the games tied.
Then OT and the D can't get a stop or force a FG.
Thats my take.
