Since the outcome was not in doubt at the time, the intentional grounding call was pretty funny. When the announcers said there was a flag on the play, they didn’t seem to have a clue as to what it was. Outside of the ref who threw the flag, I don’t think a single person watching the game had any thought that Johnson had grounded the ball, since he was clearly trying to hit a receiver (Kirtz?) who broke back instead of deep just as he released the ball. The other officials looked puzzled, but went along. I think he was outside the tackle box to boot, but didn’t bother to rewatch. Officials, I guess, have first games of the season, too.
