Retherford had this great story some time back about how, during his recruitment, Cael was the only one who actually asked him what his goals were in wrestling, academics, life/post-wrestling. The other schools were more pitching to him, like here's why you should come wrestle for us... He said Cael sat and listened to what he had to say, then mapped a path to get there by wrestling at PSU.
Same thing could very well have happened with Truax. Beyond NIL money, maybe he was sold on an opporunity and a vision.
