Fascinating. If I understand this right, a defense has less influence on whether or not a team hits their threes than anything else the D can control.
Sounds like the stats suggest that a defense is better off focusing on choking off the 2s than the 3s (like Hobbs' philosophy) because whether or not the opponent hits the 3s that particular day is more influenced by random chance than by defense. (not to say the defense has no impact -- of course it does, but teams get hold or cold from three, even when open).
I guess that makes sense -- we've all watched games like yesterday where we've missed tons of open threes (like yesterday) and games where we've buried every nearly every shot the D gives us (like Bowling Green) and that doesn't mean Charlotte's D was any better, they just got lucky we were off (unlike Bowling Green, who got unlucky we were on).
