One player left

[just another ref]

My personal opinion here is that in a very rare case such as this, a lot of rules kind of go out the window. I think A1 takes one inside position and the B players can take whatever is left, including the other inside position. If it's about gaining an advantage, I don't see much advantage in taking one position over the other if you are going to be the only one on that side anyway. On a related subject, does anyone else get really tired of having to tell the players where to get on every free throw. "C'mon, line up.
blue, white, blue, no, you two switch. That's it." etc.
Also, so many, even in varsity, just don't get the 1&1 thing. Player makes the first, and they all start down the court. "Excuse me, everybody come back. One more." Something most coaches don't spend a lot of time on?
