I had a
guy that I played mostly at center in D2. He had 56 SPD, 67 PER, and 30 BH. He shot 44/99 during his career (mostly during his SR. year) from behind the arc. I think I set him at +1, so it is possible for centers to shoot some 3's and at a decent rate. This was in a motion offense, so it might be different in a triangle.
