…can account for. There’s too much variation involved regarding individual skills/abilites of both the players shooting and defending. With regards to defensive factors that negatively impact the outcome of a 3pt FGA things like the defensive length of perimeter defenders can be significant. Also teams that have good rim protection tend to be more aggressive in their close outs on 3pt FGA than do smaller teams without shot blockers.

Another factor is the ability of a team to switch on screens on the perimeter and how they defend the ball handler coming off of the screen (do they go under the screen or fight over it?). A team like BYU has a lot of interchangeability with their perimeter defenders and are able to switch and defend on multiple players.

There are also mental/emotional factors that can be influenced by pace. Good defensive teams can affect the mental/emotional state of shooters by speeding them up when they’re more used to playing at a slow deliberate pace or visa versa.

No one thing is the be-all-end-all but good defensive teams are able to employ more of these variables that add layers of complexity and affect outcomes.
