In the immortal words of Jim Dutcher at the Jim Dutcher Basketball Camp circa 1978, "There are 250 of you here. Maybe two of you will get a scholarship to play college basketball. Your future is in school. Do your homework." Bubble burst, but wise words. We did, in fact, have one professional athlete in that camp, but he played five or six years in the NFL.
The college level equivalent statement could be delivered to basketball players with dreams of playing pro at any level. It is possible, but have an alternative close by.
