I think it makes a lot of sense to move it back for college. This will make it more like International.
High School 3pt line = 19 feet, 9 inches.
College 3pt line (will now be) = 20 feet, 9 inches.
International/Olympic 3pt line = 20 feet, 6 inches.
NBA = 23 feet 9 inches on the top side and 22 feet in the corners.
It should help create more space between perimeter and post players and should open up more room for drives to the hoop and post moves.
Of course, the women's 3 point line for college isn't moving. So, we will still have 2 lines on the floor. One for men and one for women. |
