I'm guessing you wouldn't T him up just for coming on the floor and warming up so you're invoking the rule against dunking?
Is so, what if he'd joined the other teams lineup and dunked? Or what if he had been a random fan who ran on? And why wouldn't you make them addd him to the book (which depending on the time remaining, might get them another T).
