Bullshit.TJ said to Urijah that if he would train in both TAM and Duane Ludwig's camp and Urijah gave him an ultimatum and TJ choose the guy who was the most loyal to him,Duane Ludwig.
TJ is loyal to the guy that believed in him as a more-than-average fighter. He's loyal to the guy who helped him get the belt around his waist.
TAM's coaching situation is a mess. So TJ went with the guy who helped him reach the level that TAM could never help him reach. If you look at a guy like Mendes, the he's a fantastic wrestler who has a ton of power, but his striking is miles behind where it could be. Then look at TJ, and you see how much he's evolved and learned. Why the difference? Bang Ludwig.
