If a broker came to the NCAA and signed a statement that saying they paid Johnny for autographs, the NCAA would probably act on that--Johnny could deny it, but if they had any other credible evidence supporting the claim, they would probably go with a mere preponderance pointing toward a violation. But, without a statement from a person involved, they are going to want some pretty high quality cir stantial evidence before taking any action, and it doesn't appear that they have any such evidence at this point in time (they don't have the most recently release videos, and probably never will since they were illegally recorded without Manziel's consent).
