Big Shot: Confessions of a Campus Bookie (2002)

Mother's good boy Benny Silman from Brooklyn becomes an economics student at Arizona State University for the sun and sexy girls- and the proximity of gambling paradise Las Vegas. Benny aces his studies, being a mathematical genius, but the one who earns money from him at sports is bookie Troy, who however recruits him as subcontractor, making a few thousand for himself. The next year Benny starts for himself, with a few dozen student vassals, and makes a hundredfold.
