I heard today on the Big 12 radio channel that Davis, had been a coach on 3 staffs that won a national championship in football, so he has been around winning programs and know what it takes to get there.
The hosts, both former players said they had spoken to many others about the situation, the majority had no problem with what Davis said and it was only people that had never been in a locker room that objected to it.
The coaching staff at UT is trying to set their Culture in place right now, in their first season. They are basically telling the players that the way they played is not acceptable and if you are not OK with that, then its time for the player to leave the program.
You only get opportunity to set the culture in that first year, so you have to make it plain to everyone, what is expected and anything less than that is not. If any players is not fine with that, then leave, its really a simple idea.
