I trained some JR players in Utopia. My SF Ettig is my best scorer. He has 50%+ 3pts and a little bit under 60% FG. I'm pretty sure he would score 40-45% of his threes in D2. And it doesn't matter if I play an outside or inside offense, he will still be the main threat because of his skillset. And I think if I had better passing at the other players, he would get even more better shots.
How high did you end up getting his JR up to?
I'm currently in the beginning stages of some exceptionally non-standard builds for my three trainees, so in a couple of years time maybe I'll have half the reputation you do for your unusual builds (though mine will almost certainly be very expensive and relatively useless, I figured I wanted to try something off the wall).
