I'm still only cautiously optimistic. Playing a good defense can have a significant impact on shot percentage.
KU, Baylor, and West Virginia have really good defenses through the OOC. Others are solid, but I'm not sure we'll see great defenses night in and night out in this league.
Also, 3pt% usually doesn't drop much in conference play and often gets better; the regressions will come in TO%, 2PT%, and maybe OR% against better defenses. Tougher 3PT% "defense" in league play isn't a reality.
