I tend to agree with Jim in this side debate. They practice free throws plenty. For example, I watched a game they play in practice where the team shoots free throws and we get 1 point for each make and the opponent gets 3 points for each miss. Mason won both times.
They run plenty of sprints. Losing team in every segment of practice gets to run. I heard they had to run something like 150 laps around the Gym after the BC loss. So, he isn’t going easy on them if that is what people think.
A third point on free throws, if you read the book that CKE recommended, “The Talent Code”, the Shaq free throw phenomenon is discussed specifically. They suggest he was probably training wrong and only practicing free throws from the line whereas he should have tried it short sometimes and long others to learn to modulate his shot.
