Why we’re looking at deep 3-pointers all wrong in college basketball

I didn’t mean to stumble onto a Jay Wright secret … but that may have been what happened this week when I started to research a potential blog topic.

Recently, I’ve been fascinated by the work of analyst Will Schreefer, especially when it comes to the excellent (and free) shot-chart tool he’s created for college basketball players.

And one thing, in particular, interested me: his breakout on the site of “NBA 3s.”

So I wondered how KU fared when it came to this aspect. I sent Schreefer a message, and he was nice enough to send back the data that he’s compiled from available sources online.

The verdict? KU was a good “NBA 3-point” shooting team last season. The Jayhawks made 38.9 percent of their long-range 3s, which was well above the NCAA average of 34.5 percent for those shots.

Something else caught my attention, though, when Schreefer sent over the results by team.

NBA 3s made-NBA 3s

att., Missing games

Villanova 327-832, 2

Michigan 249-691, 3

Marshall 240-673, 0

Wash. St. 231-623, 0

Utah 219-608, 0

Oregon 211-605, 2

Marquette 258-604, 2

UTSA 202-593, 1

Seton Hall 224-589, 2

Gonzaga 217-585, 3

Auburn 210-585, 2

Florida 218-580, 3

Kansas 225-578, 3

Before going further, let’s get a couple of needed caveats out of the way.

1. The above leader-board does not include all Division I schools. The site Schreefer uses has data from about 40 percent of games, which includes a heavy emphasis on the Power Five programs. You can see the number of missing games from the sample on the right of each school above.

2. The shot-chart data Schreefer uses appears to be entered by hand, so the length of shots is an estimation. This means it won’t be perfect, but without camera tracking like MLB has, it’s about the best we can do for now.

Having said all that … the top teams above are intriguing to say the least.

Villanova — by far — leads the way. While this shouldn’t be shocking (Villanova took a lot of 3s last season, so it stands to reason that some of those were from distance), it is worth noting that Wright likely wasn’t limiting his players to only attempts with toes right behind the line.

The Wildcats’ national championship foe — Michigan — is second on the list, and that’s even with three games missing from its data set.

And in third place? Marshall, which actually makes sense considering its coach. Dan D’Antoni — his younger brother Mike is the Houston Rockets’ coach — became a darling of the basketball analytics community in 2016 following his postgame rant about the value of 3-pointers.

If we trust the data to be mostly reliable, those three teams clearly put themselves ahead of others when it comes to shooting long 3s.

And though I hadn’t thought about it much until now, those squads could be gaining an edge by doing so.
