If you do the physics on that.... the underhanded freethrow is the best way to go.... just so "uncool".
You see.... on the underhanded freethrow the ball's trajectory travels to a point where the highest point of the shot is barely above the rim. Thus, there is less of a chance of hard bounces off the rim.
Yoi.

yep, there is an old guy that can make like 99.something% of his free throws and he shoots them "granny style"
