Cuban went to Pitt for like a semester as a freshman undergrad after leaving high school early, and transferred to Indiana. He has always donated to IU. He never went anywhere post grad.
For the life of me I will never understand why so many Pitt fans think that a guy who was in school here for such a short period of time and who is an actual alumni of a different P4 school would ever be a Pitt donor of any sort.
But hey, he did come to that one basketball game here one time.
