He certainly could, but he's going up against long odds. His margin for error is incredibly thin. For the overwhelming majority of players in the NBA, they need to meet a baseline requirement of height/weight/vertical/quickness etc. just to get a spot on a roster. Mason doesn't really come close from that aspect. It can be overcome with supreme skill, but as I stated his execution would need to be essentially perfect in order to overcome his natural shortcomings. Trey Burke and Tyus Jones are good comps from an athleticism standpoint, but both were far more skilled as college players than Mason. By far the most likely scenario is that he earns a decent paycheck for a decade somewhere in Europe and hopefully for his sake never has to sit in a cubicle for 40 hours per week.
