I don't mean to sound condescending here, not directing this at anyone in particular, just a perspective motivated by "we shot well":
I often see folks stating or insinuating that good three point shooting in a particular game is largely up to luck. There's a component of that for sure, it's a high-risk / high-reward shot, but it's also one of the most well-practiced and designed-for elements of modern offenses, and skills for players with pro aspirations, you're not getting a spot on most pro teams and most levels if you can't hit an open three at least.
We shot well yesterday because yes a bit of luck but also because KU deliberately gave that shot up to Tre King. They also deliberately put a slower, less athletic defender on Keshon and gave up those shots to him.
Similarly, teams shoot and make a lot of threes against us, often above their averages. That's by design, our defense takes away basically everything else from most teams and while TJ's defense is super-effective, the book on how to beat it is open: the trap/double is coming, don't panic, swing the ball or get it cross-court and you can get a lot of good looks for three.
