I don't know what to say about this but Duke stands out both for the relatively low number of scoring runs we produce but also for the very low number of scoring runs we allow.

I think it's also somewhat random. I mean, an 8-0 run followed by a basked for the opposition followed by a 9-0 run would be a 17-2 run. Which would be more impressive than a 10-0 run followed by a basket and then back-and-forth thereafter. But the 10-0 run would count, whereas the 17-2 run wouldn't.
That said, it's not surprising that Miami has the most, because they have streaky guards and generate turnovers.
