If only it ended up like that for more than a few.Why not declare for the draft? There really isn't any downside. Make sure you communicate with your coach that you're going to pull your name so you don't cause issue there, and you're set. You'll get feedback from the NBA.
I doubt many of the players today who are playing only one year would have played at all in the past. The one year done and out really changed things. College was never on their horizon then. I always wonder how weak the college load really is for these one and done players.Maybe I was just naive when I was younger, but it sure seems like players hate college more than ever.
