I don’t know exactly who to blame for the delays but I imagine having a rookie qb running the game management, everything is just slower to click.
After watchng a replay of the whole game, my blame goes to McDaniel.
There seemed to be no issues for two and a half quarters, then 5 minutes into the third quarter there's a notable delay in the plays being relayed in time to Skylar before the huddle. With 9 minutes to go in the last quarter I notice him and someone else checking his communication equipment as if it's an issue. The rest of the game is pretty much a disaster.
It's a rookie mistake by a young head coach - between the crowd noise in a hostile environment and having a 3rd string rookie as your starting QB (as well as this being the first playoff game for a lot of guys out there) he's just got to get the plays in quicker.
