Arkansas approached him about their coaching vacancy. It is a pretty high likelihood that he intended to leverage that to get more money from UK but by talking to Arkansas without notifying UK he violated his lifetime contract and there was zero chance the AD was going to let him off the hook. He thought the fans were going to revolt and demand he stay but when that didn't happen he left.
Sorry but no way that is true. By then, it was very clear that UK was done, happy to have Arkansas take him off their hands, and that there was 0% chance they would pay him more. Cal knew it too.
