clip.

Look at the very first frame of the RedditCFB tweet (from the Yahoo article) that is titled "Here's where the #MiamiBeachBowl fight began:" Notice the left hand of the Memphis player on the very right side of the frame. He is pushing #56 (Koroma) of BYU in the back. #56 then goes into #97 of Memphis - pushes him and immediately turns around to see who pushed him. #97 sees it as a sign of aggression and jumps #56. #56 is then jumped by four Memphis players and the brawl begins. Koroma was jumped. Period. First by a Memphis player I can't see the number of and then by #97 and then by others.
