Max Eberle graduated (not sure but believe his degree was in English, will have to check with him on that)
Believe Charlie Williams may have graduated (he too was a Pool Scholarship player)
Gerda Hoffstatter graduated a few years ago from NYU
Oscar Dominguez is still attending college in Cali (think maybe he is a Junior Pre-Med student)
Examples of gifted players who put their education before pool: The Rankins and Callado's in California.
I strongly encourage players to further their education. While a player may or may not make money on the professional side, it has not proven to be life sustainable for most, only a few. It is still possible to play competatively, enjoy it and still further your education thus offering a player more opportunity in a wider spectrum of areas professional in addition to pool. There are so many online options through reputable colleges that a player can even get their degree while traveling around the country and world.
Sad, I've met too many players who were talented but realized that playing in pro events or being on the road was not only tougher than expected, but did not work for them financially. Too many find themselves with little stability or a "pot to p%*& in" when they get older.
