Football is the ultimate team game. Brady got totally killed all game long, and was under pressure on the 2-point conversion as well.
And yet..... he should have made that play, and even in a moment of total honesty (not just playing the humble leader for the cameras), he would, I'm pretty sure, say he just missed this one.
The first second after that ball was snapped he should have been able to see what would be open, given how Denver reacted to the two receivers right of the hash marks.
Obviously Brady is incredible and anyone can make a mistake and lord knows he's been amazing. But he didn't get this one right. Huge bummer, but there it is. Gronk was indeed wide open.
