Delayed entry after inbounds pass...

[HokiePaul]

If I notice a player just hanging out after a throw in (not purposely delaying but just oblivious/unaware and in no hurry to enter the court), I'd probably remind him not to delay returning to the court if he came for another throw in.

Fortunatly I have never had this call. I think that the time would be less important than the intent. I'm going to give a lot of leeway if they are just observing the play (it may not even be "purposly delaying" anyway if they just "forgot" to step onto the floor). However, if it is part of a designed play to trick the defense, then there would be very little leeway as it would clearly be purposely delaying.
