Tough loss.
Not too much to say other than last night shows why just because you're on the one yard line that NOTHING is guaranteed. That is why I never fault a coach for challenging if they get a first down on the one instead of being given a TD if it looks close. Nothing is ever a given in this year.
The muffed snap definitely hurt, but I don't mind the call to Gronk. You're going with your two best players against a defensive player that's not great in coverage. Gronk just got his feet tangled up a little and stumbled. Great game, tough loss.
