I'm not sure what this guys deal is, but what the hell is going on? I've never seen this much chippiness from a sideline coach and nothing is getting flagged. Here's exhibit A:
There's absolutely no history between these schools and for this to keep happening is complete and utter classlessness. Even if there was history, there's absolutely no excuse for this kind of behavior from someone on the sideline in any capacity, much less the team staff. I've always had respect for Coach Sumlin, but this is ridiculous. I'm sure nothing comes of this from a league or NCAA standpoint and that's also a shame.
UPDATE: The staff member in question is student assistant Mike Richardson. ESPN is reporting that he wasn't allowed back on the field after the first half. Kudos to Coach Sumlin for removing him from the sideline.
As soon as Coach Sumlin was made aware of the sideline incident, the student-assistant was told to remain in locker room for 2nd half— Texas A&M Football (@AggieFootball) December 29, 2014
