As to whether the ball was in air:

8:48 he starts delivery. A split second later, still 8:48, ball well out.

Cam pans at 8:47 & Kelce is flat on his back.

2nd angle shows contact @ 31, thrown @ 26, lands 22.

We’re pretending Mahomes can’t see the start of that & take a shot? pic.twitter.com/Io07uHWSjy
