can't see the lead calling the sideline up to the free throw line extended.....who is watching the post...you have a trail over there to take care of that...i do think they do something like that in women ncaa though, not sure!! i have heard something about it! i've never done it so don't know if it would be better, but doesn't seem like it, because you would have to rely on knowing your partner has switched from sideline to post when you switch from post to sideline... kinda crazy to me!!!!
