Whitehead had clear possession of the ball when a SJU player subsequently grabbed him across his body. Why isn't that a foul?
With that said, SHU was very lucky to escape with a win as SJU made several terrible plays in the final minute. For example, they shouldn't have even fought for the loose ball on the Whitehead play. SHU would have had the ball down by one near the St. John's basket with only 5 seconds left and no timeouts.
