I can say is that in my view, the Lohners can straight up shoot like Jimmer.  I remember his uncle playing ward basketball and nearly single handedly destroying every one of the opposing teams in the stake from 3 range, just effortlessly.  It seemed so easy, I couldn't believe other people couldn't shoot that easily, and I remember growing up thinking it's just a matter of age, and it will come to anyone who practices.  No, there's something extra there.  

So, I wasn't surprised at all to hear that his nephew was a great shooter in high school.  I think he has the gift of good genes on this issue, so I'm sure he's as mystified as anyone.  I hope it comes back to him.
