I see 3 main problems. I 'think' they're all fixable.
-Our free throw % is 62.9. That's 309/334 teams in D1. (how many of those are front ends of one and one's)
-Consistent rebounding effort
-making shots inside 5 ft with or without contact (DG and others)
I would agree, and would add......an inability to defend the 3 point shot. Not that you have to block them, but at least make them a little more difficult to take. Also fixable.
Plus, there simply has to be more movement in the offense, and more crisp, quick passing. The offense moves very, very slowly. That is why they have so much trouble getting the ball inside. It is not hard for the defense to prevent it.
