And several of those were the front-end of a 1:1.

Back in the olden days when I was at BYU, I had declared as a Coaching minor, so I took a basketball coaching class from Roger Reid and Tony Ingle and part of the homework was to go to the Marriott Center and watch a bunch of their practices.

One thing I remember is that they really emphasized practicing free throws, and they would always make the team stop and shoot FTs immediately after an exhausting drill, so that the players would be tired and catching their breath while they were shooting FTs (presumably to simulate in-game conditions).

I don't know how KY handles that in practice and I'm not remotely qualified to question his coaching (and maybe that's just not a skill set of players nowadays), but Reid's teams in 1993 and 1994 shot 77% from the line, and this year's team is at 68%.
