The Patriots were in a tough spot and they needed a "lucky bounce". They got it. End of story.
People talk about a “lucky bounce” for the Pats, but I think the pendulum on this is 180 in the other direction.
Seattle needed a lucky break to get to where they did on that play, and the defensive back made a great play to defend, but the ball took an insanely favorable bounce for Seattle. I give the receiver a lot of credit for catching it, but...most objective observers would agree it was a highly improbable placement of a deflected ball to fall where it did to be caught.
I think the interception by Butler was a far better conceived individual effort and pure football play than that crazy catch that put Seattle near the goal line.
That catch on the ground isn’t likely to happen again like that in hundreds, if not thousands of iterations.
That read by a defensive back, knowing the offensive set, and reading the play to make a athletic break on the ball was a well executed play. The only luck on that was having the pass play called instead of a run play.
And that isn’t luck...it is a mistake, in my opinion.
