Had he dropped the ball, yes, but he caught it. The call would have been an unsportsmanlike penalty and would have been tacked on in addition to the yardage gained, not an "either or".
Plus, those who choose not to pay to watch this game can still get their fill of Mahomes and Maauto thru the endless stream of f'ing State Farm and Campbell's Chunky Soup commercials during all of the other games. Win-win for 'Robber' Goodell.
