@LeftOn172nd At the exact time his shin hits the turf he still had possession so down by contact with ground. Where ball goes after down is inconsequential.
@CFBDouchebag Once the arm is hit when in a throwing motion the trajectory of the ball may go different from the intent. Obviously the back was blocking so possibly not intended receiver. Need more video than this alone
@tjmcaulay Here is my take. The defender is several inches shorter than the receiver. He leads with his shoulder but when taller receiver ducks his head the helmets also hit. Pretty simple. The “defenseless player” absolutely sees the back coming and prepares for hit. Excellent no call.
