i think Pomeroy has proven over the last two years that giving up anything at the rim to defend the 3 is foolish. People can't continue to ignore the data and expect to win.
Below is one piece he did which proves paradoxically that the best way to defend the three is to defend the two pt FG.

Another widely believed myth is that good FT percentage is correlated with winning. That is decidedly not the case. Which is why FT attempts is one of the four factors of winning BB, not FT % makes.
FTs were one of BYU's strengths last year, not the other way around. They led the nation in FT attempts for much o f the year and finished among the best in FTA even adjusted for tempo.
The modern stat gurus data are part of NBA coaching religion but many college coaches continue to believe the old myths, like the old time coaches in Moneyball with whom Billy Bean had to cope and eventually dismiss.
