So I was discussing running the endline following a time out with Brandan89 tonight, and we came up with the following question:

Team A scores, B completes their throw in when the head coach of B requests a time out, the officials grant his request and the subsequent throw in will be on the endline. Is B able to run the endline or is this a designated spot throw in??

No, not if the throw-in ends prior to the TO request. It would be a spot throw.

If B completes their throw-in (which you said they did) there will be a spot throw-in after the TO.

Unless you are in Washington state. :D

Yep for the time being, but we're working on getting that fixed. Stand by, possible "change in interpretation" coming soon from the Washington State interpreters thanks to a little pressure from a couple of us who are regulars on this board. Power to the board. :D

This is another case where I'd like the time-outs given back to the players. Team A scores. Team B coach requests a time out. While you are hunting around for the head coach, make sure it's him, turn around, Team B has already inbounded the ball, when he actually requested time out before the throw in was made. So you grant the time out, now you have to award a spot throw-in, rather than run the baseline, which is what the coach wanted.

While not really correct, most officials allow the team to run in this case.
If you really want to be strict about it, you could tell the coach that his players should have been looking for his TO request as well, perhaps even making one of their own, and not inbounded the ball.
Oh, if you are using a shot clock, you have to reset it if you are going to allow the team to have the endline.

If the coach calls for timeout before the ball is inbounded and it takes me a second to recognize it, I'm giving them the end-line throwin rather than the spot throwin.
Same principal as when A1 grabs the ball and calls timeout just before falling out of bounds. The whistle never blows before he lands out of bounds, but you give him the timeout anyway. That's because you grant the time out based on when it was called, not when the whistle blows.

How is this not correct?
