[Ref in PA]

This could be just me, but I don't think I would have the presense of mind to know if A5 was the correct player that should be in the game, especially after a lengthy, confusing substitution. A3 might have also come off the floor. So the coach can essentially send back on the floor any one of the players that came off. I am not even sure I would notice if A8 came off the bench rather than A5 - especially if A8 had played earlier in the game (which should be a T for not reporting). Basically, this interpretation is giving a pass to team A because the refs did not follow correct procedure for not counting prior to administering the inbounds play.
