I always got the vibe faber cares more about his control and influence than having people in there that could actually train his fighters with a different perspective.
Just look at Fabers fight IQ during his career for starters. Exciting but not very bright.
Then you see how much TJ evolved as a striker under Ludwig. Regardless of what went down between Faber and Duane, its undeniable TJ became a much better fighter once he worked with Duane at TAM and all the drama went down.
Fabers a loyal guy but I dont think he cares about his guys realizing their potential if hes at risk of not receiving the validation he desires. He also takes things that are common, such as training with other teams in mma, and brands them as treason. Why would anyone want to go train there if it means that this guy might label you a snake the second he doesnt have control of a situation.
I always felt chad and benavidez could have developed even more. Chad had championship talent. Even look at Cody right now. Makes you think.
