Noted at the time on GDT, looked to me like the ground may have helped secure the catch.
The one that bugged me was the Guyton push-off OPI on the first Hail Mary. Bills accepted the penalty and then they completed Hail Mary 2, but Guyton didn't appear to secure the catch to the ground even more than Williams. It would have needed to be a booth review but if they had overturned the catch, Bills decline the OPI and the game is over right there. Dunno why they didn't at least review.
Oh right. NFL refs have devolved year-over-year since forever...
