The word through the grapevine was that Kyler Murray didn't play against Ole Miss because of how Jake Hubenak practiced during the week. That seems to be partially true.

As previously mentioned, John P. Lopez of CBS Houston wrote a pretty damning piece about the state of Texas A&M football with Murray at the center of it. One report from Lopez is that it was Murray cursing out Spavital during the Alabama game that lead to the freshman's demise:
Hence, when Murray was yanked in the Alabama game after throwing an interception, he went full F-bomb on Spavital and his fate for the Ole Miss game was sealed.
Hubenak likely had a better week in practice because, as Lopez reports, Murray didn't get any first team reps, which caused further division among the players:
Some players also believed Murray should have been left at home, rather than face the embarrassment of national television cameras focused on him any time Allen made a mistake. Then, the worst-case scenario happened. Allen wasn't just bad. He was awful. And there was Murray, shamed on the sideline, for all the college football world to see.
There's no video/audio to back up the reported exchange, but as the old saying goes, "Where there's smoke, there's a fire."
