My Window of Playing Professional Basketball is Rapidly Closing

A few years ago I was invited to play against the Harlem Globetrotters as part of their show.  It was an incredible experience, and one that keeps me returning to the Globetrotters shows year after year.  However, I am a little disappointed with the NBA since no team has called to even give me a tryout.  Hello?  I went downtown on the FREAKIN' GLOBETROTTERS!  What's a brother gotta do?
