Not entirely true. Anyone who's EARNED their PhD might very well have a brain worth preserving, but there's many PhDs out there who purchased their doctorate from degree mills, and are dumber than a box of rocks.
Everyone has a brain worth preserving...my point was when you google "John Urschel", most of what the news has to say about him is that he is a Math Genius, because he is doing his PhD at MIT, which I don't believe is the case.
I'm pretty damn impressed at ANYONE in the NFL with a secondary degree, but a Math PhD at MIT? That's incredible. This guy is clearly athletically and intellectually elite.
No, he's considered gifted in math because he has more than a few papers already published and in review. That's noteworthy for a guy who just started his PhD
