Glad you’re not a referee.

No. It’s only legal for the kicking team to advance a scrimmage kick if it’s recovered behind the LOS.

Runners are not defenseless. The defender did not initiate contact with the crown of his helmet. There’s literally no case for a targeting call on this play.

The umpire was looking exactly where he should have been looking. The receiver split at the bottom of the screen was the field judge’s key. If you don’t know anything about the mechanics of officiating the game, shhhh.
