Does anyone remember?

[Jurassic Referee]

In days of old.....

Before the 3-point arc, anyone not on a lane line had to stand behind the freethrow line extended to the sideline and outside the FT semi-circle.

And way back...iirc...they could stand below the freethrow line but had to stay some set distance from the lane line...like around 6' behind the end of the lane space. I could be wrong on that one.
