Also don't forget about the 3 point line too. Barry Stevens played when there wasn't one. He may still have been #1 scoring leader.
No, he wouldn't have. Barry would have needed 313 of his 880 career baskets (over 35%) to have been behind the arc to stay ahead of Grayer.
The ISU three-point record is 270 (Sullivan).
Grayer only had the arc for his last two years. He made a grand total of 27 treys out of his 540 FGM (5%) in that two-year span.
