It's just tough for players to make the NBA and stick. I mean look how many great college players over the last 10-15 years have flamed out in the NBA. Jimmer Fredette, Trey Burke, Frank Kaminsky, Frank Mason, Luka Garza. And those guys were NAISMITH AWARD WINNERS that flamed out. It's tough to make the league and stick. You have to either be a super stud or have to accept a role. Most players aren't the first and refuse to do the second.
