After rewatching it 2-3 times, the ref on the sideline closest to all the action who didn't make any call is most at fault. As a referee, you are taught that if you see a call, you make a call, regardless of whether it is in your zone of coverage on the floor or not. The travel call was the most blatant...both the Eastern Michigan player who initially grabbed the rebound and then the Ball State player who ripped it away both got away with extra steps (Ball St. player actually traveled TWICE within the sequence).
The refs want to let the players decide the outcome, but you have to call the game as it was intended, especially with those violations. What refs don't need to do is call every tick tack foul of a player with his hand resting on the hip of the ball handler, a rebounder who reaches over a player in front of him, etc.
