Delay by free-thrower after TO

Thanks JT.
This casebook play clearly says he is not allowed to enter. Which is what I was seeking.
Although, how the rules committee got this interpretation, I don't know, since the rule book doesn't mention entering only leaving.
But hey, I'll go with it.
PS Welcome to the board and also we cite rules with dashes 9-1-7 and casebook plays with periods 9.1.7 as they are written in the books. This will prevent confusion when others read your posts.
