Can he be an antagonist? Sure, but he is also an on-air personality so the more listeners the more revenue his show generates. He also plays on the Purdue faithfuls emotions especially when it comes to Indiana's tourney success compared to Purdue.
And that is the issue with him for me. I can't stand the Radio personality Jockitch, so I'm not going to like him on TV either. And you saw what happened at MSU, which came up again during the Purdue broadcast, you can't separate the two.
At the end of the day, he is an egotistical jackass who says only people who played or coached knows what going on in a game which is complete crap as there a lot of people who have been around the game their entire life, so they do understand it really well. His ego gets in the way of him being good, so I have to turn down the volume when he does games.
