If you are good enough to make the team, why would you not want to play on acollegebasketball team.
It depends if your family can afford to pay forcollegeand you are receiving scholarship offers from smaller schools. See Michael Jordan's son. He could have gotten full or partial scholarships at some smaller schools, but decided to walk on at Illinois for the competition and atmosphere.
Your question is not detailed enough.

Did you had any good games against guys that are going tocollegenext year?

Do you play against grown men that are professional overseas or recently retired? I mean really, who are you playing against that leads you to believe that you are good enough to make the squad? Even a Division II school will have talented players.

Are you prepared to be a "practice player" for at least the next 2 years? That is assuming you are a Freshman incollegeor still in high school now.

Do you really want to use up your studying time at practice? It won't be anything like high school. There is a lot more weight lifting and you will be playing against grown men in top physical condition in practice. Don't take it lightly, there are all kinds of people out there playing ball.

Good luck.
