Yes. Based on my observations, they normally float between 2 conferences. Adams and Shows normally do SEC and AAC. The AAC has games on Thursday's and Sunday's. I can't say that I have seen Adams officiate a Big 12 game though. He has done other mid majors though because he kicked out a young radio guy for a mid major team a few years ago. You should be able to google that story.I don't know. That's the 1st time I've noticed him out of conference during the SEC season (I don't watch a lot of Big 12 games). I didn't think referees floated between conferences during the season.
*Maybe Vegas initiated it.
