Reset the ten second count?

[Texas Aggie]

If the L is still in the backcourt, as the original post said, then the ball had better still be below the back FT line.

It isn't where the ball is, but where the players are. If there are 7 or 8 players in the backcourt, which isn't uncommon, L being around the division line, regardless of where the ball is, may not be out of line. Besides, that sideline is the lead's call and while he may be moving down toward the baseline, he has to be aware of what's going on if there's a pass over to that area.

I have seen traps where the ball is as far out as halfway between the free throw line and old 28 foot line, and there are still at least 6 players in the backcourt or right around the division line. This will typically happen in sub-varsity games or in games where the offense doesn't know how to be a full press or full trap. Keeping a half court distance relative to your partner is the general rule, but there are exceptions.
