I think calling it a “hip check” is a bit of an exaggeration but the ref absolutely intentionally leans out to make contact with him. Doesn’t throw the flag during the phantom “taunting” but waits until after he bumps him and the player’s halfway across the field back to the Bears sideline.
Marsh, being a journeyman practice squad guy, would be lucky to play in the league ever again if he’d intentionally leaned out to make contact with a ref. There should be similar consequences for a ref that intentionally makes contact with a player.
