Can't remember when it happened but Tanny almost threw a pick. Went threw the corners hands to I believe Jennings and they marked it short of the first down. Replay showed he caught it a yard past the first down but momentum brought him back
Forward momentum only counts if the defender forces you backwards. Jennings was untouched, so the forward momentum rules does not apply. He came back, short of the first, on his own power. It was 100% the right call.
