It's not about "not hitting" him. You can hit him just like any other receiver in the act of catching the ball.
You can not hit a player in the head if he is in the act of catching the ball.
Hits to the head are illegal to defenseless players.
Had he caught the ball and took a step, there would have been no penalty on Brandon Harris, because the "runner" has the opportunity to brace himself, tuck his head, or roll with the blow.
