NBA players dont have to ( like kobe)
You would not be in the NBA if you did not go to college.Update from Asker: Players such as Lebron James, Brandon Jennings, etc...
Getting into a college to play basketball is much easier than getting into the NBA. About one person from every 2 high schools will get an opportunity to play for a college.
You can play for the school u go to and that is all
Get Your Ged, Go To Junoir College And Then Go To A College And Play College Ball.
At least 1 year
at least a few years
University of Arizona
there are none, but the age was changed 2 years ago from 18 (or just out of high school) to 19 (after freshman year of college) but you can go to Europe to play professionally there for a year and return to the us at 19 and enter the draft.
It all depends on the sport. In football you have to play through your junior year. In basketball you have to play one year now. In baseball you don't have to play at all.
Louisville, Duke, U. of North Carolina, U. of Michigan are some big basketball program colleges. but to be in the NBA you dont HAVE to do college.
