I’m watching the replay of the 4x400, looks like Burke finished up the 3rd leg of the race with Memphis right behind him. Both runners handed off and went to the side with Burke bending over. Memphis runner came over and said something to him. Next time around, you can see Burke getting heated with the Memphis guy. Next time around, there are folks trying to hold Burke back. Then they pan over to the sidelines and the Memphis anchor is talking crap to Lattin who is following him. Hawkins comes over to try to break it up, and then it looks like a Memphis coach comes over and puts an arm in Lattin’s chest to back him away. Got Memphis and Houston runners yelling at each other.
There was nothing during the race that would have caused animosity. Guessing that the Memphis runner came over and told Burke that he was gaining on him or something after they finished and Burke took exception to how he said it. Good ole Classy Memphis.
