I know that there's supposed to be some kind of rule (or it may just be a "guideline") that players with more than 3 years NBA experience can't play in Summer League games, but how many times are you allowed to bring a guy back who's never played in the league?
Let's say, for example, there was a guy who played basketball in college, and went undrafted. He didn't really have a serious desire to play professional basketball, but he wanted to be able to "rub elbows" with the pros, and he had a hookup in the front office who kept getting him tryouts for the Summer League team. Presuming that he was actually good enough to make the Summer League team, how many years would said guy be allowed to play, before they told him he couldn't play anymore?
