I think a player should instantly pop in the free throw skill after he attempts 200. Then 500. Then 750. Then 1000. That would easily prevent things like that from happening. Or simply do what others have suggested and made free throws correlate with jump shot (Every 3 or 4 jump shot pops also pops free throws once).
