There is evidence. Texas AM just landed the best class in NCAA history coming off of a mediocre year where it just happens to be the first season where NIL money is universally allowed.
That is circumstantial evidence, but this isn't court either. It was super curious when Hugh Freeze signed the best class in OM history by leaps and bounds too. Wouldn't you know it, he cheated. NCAA football is not an unstable landscape. When something unexpected happens, you are right to be skeptical 99/100 times.
There's no evidence Deion payed those players either. Thoughts?
