“It’s something that I always ask myself, exactly where do I want this to go,” he said. “There’s a lot of conflicting thoughts about that. I don’t really have any basketball background.”

Pomeroy said he does a few write-ups each week for Baylor, crunching information not available on his site. He said he tailored the information to what Baylor was looking for, like studying opponents’ fast-break percentages, which can determine how many players Baylor sends to the offensive glass. He said one of the frustrating parts for him is how to better communicate the information.

“I wish I knew how I could tailor this information better to help coaches,” Pomeroy said. “I can’t communicate information the way that I read it, because it will overwhelm them and make their eyes bleed. I feel like I need to whittle it down to two or three highlights.”

Programs like Virginia Commonwealth, Ohio State, Marquette and Butler use KenPom’s statistics as a complement to Synergy Sports Technology, a video scouting system that has become popular in the past five years. (The full Synergy package costs $5,000 to $7,500 each year.)

Synergy is so advanced that the Butler assistant coaches Matthew Graves and Micah Shrewsberry said they could take a player like Old Dominion guard Kent Bazemore, whom they faced in their first game of the N.C.A.A. tournament, and find out that he drives to the right 75 percent of the time (despite being left-handed).

The Synergy statistics back up what is shown in the clips. With a few clicks, Butler coaches can watch clips of every post move on the right block that Wisconsin forward Jon Leuer made this season and how many times he turned over his left and right shoulder.

“It reassures us what we saw,” said Darnell Archey, Butler’s coordinator of basketball operations.

When George Mason’s Mike Morrison missed his first field-goal attempt against Ohio State in the Round of 32, Ohio State forward Jared Sullinger pointed to Kuwik, the video coordinator, on the bench. He had used the go-to move that Kuwik showed Sullinger in film that week.
