gaucho, put the numbers away for a second and just use your eyes. We both know it's simply down to our bad defense. Sure, going 50% from behind the arc has some luck to it, but overall, if you put the numbers away and just watch our defense, you know as well as I know that it's down to our BAD defense.
What happens on a typical opponent's made 3? Their ball handler drives in the lane, 2-3 of our guys collapse to "help," the ball handler kicks it to a wide-open shooter who is already set. Shooter catches the ball, already squared up to the basket, no dribble required, pauses a half second to gather himself since he's wide the F open, and then pulls the trigger. Or... and this is another favorite of mine... our defender will run way, way under a screen, leaving the shooter wide the F open from behind the arc.
Yes, there's some luck associated, but our awful 3-point % allowed isn't down to bad luck, man. It's down to bad defense. It's not like teams are having to attempt NBA style 3s of dribble, dribble, crossover, step back, contested 3. Nope. If teams were doing that against us and shooting 50%, I'd call it bad luck. Nah, this is just bad defense. Near every 3-point shot opportunity we allow is a wide-open look. Yes, sometimes the opponent makes a prayer from way back as the shot clock expires, or makes a contested 3, but dang... if you let a team get hot by nailing wide-open looks, then they're gonna start making some of the tougher shots with that built-up confidence.
