I'm sure McVay will be the first person to accept responsibility. I always think he'll obsess about it during the off-season, but he'll utilize this game to motivate himself, to get smarter, and find a way to use the experience moving forward. At some point during the NFL season, 31 teams will walk away empty-handed. For those teams, it's the experiences you make and how you use them going forward that counts.
That being said, and even though the entire team seemed off all game long, I still think this game was ultimately decided by three situations: 1 and 2/ Cooper's two TO's, that spotted the Falcons 10 points; and 3/ Brockers injury, which the Falcons utilized very well to just run it time and time again in the gaps he vacated. I'm not looking to assign blame, Cooper will bounce back, and he did so well last year, it's just a fact, though, that losing the TO battle like that WILL lose you a close playoff game. I think the team could've recovered from their below-par performance if not for those turnovers.
Still, this season was way more than I had ever hoped. Use the experience, come back next year and retake the division, and then go on to win a play-off game. That has to be the goal.
