It would be a very low number, like 3 or 4% overall. Guys who enter traffic or shoot later on the shot clock probably get blocked more often. Here just a sampling from a few starting guards last season: Rip- 3% Billups- 5% C. Paul- 2% Nelson- 2% Wade- 1% (Stuckey's idol)... Wade gets blocked 9% in the paint. Redd- 2% Rondo- 5% (another guy with a bad J) After looking around, it looks like getting blocked around 10% on attempts from the paint can be acceptable for an aggressive PG. From the outside, the acceptable limites are generally up to 5%ish. After that, you have a problem.
