The story of the game was definitely the OL, particularly the interior, getting whipped. They were obviously horrendous in the run game and that last sack was on Martin/Frederick also.
Prescott was ok but the offense had very limited opportunities with the Saints offense seemingly able to do nothing but hold the ball and bleed the clock. Throw in a few dropped passes, some untimely penalties, the two fumbles (Elliott's wasn't of course), and it was just enough for the Saints to fall into a very odd win.
The play-calling definitely seemed uninspired but I can't really assign blame. I already think Garrett is a mediocre HC at best, we'll see on Moore, but ultimately this game comes down to the interior OL getting consistently whipped, and perhaps Moore's inability to pivot off of that.
