Trench Chess: CMU Sophomore Uses NFL Data To Examine Pre-Snap Play
Media Inquiries
Six-year-old Abhishek Varadarajan watched with his family as Eli Manning and the Giants defeated Tom Bradyâs Patriots in Super Bowl XLVI, a game that kicked off his lifelong love of football.Ìę
Now a sophomore at șĂÉ«ÏÈÉúTV, Varadarajanâs gaining yards toward his own goal line: a career in the NFL. His project â,â a semifinalist in , analyzes different ways a defense can create confusion at the line of scrimmage.
Raised in New Jersey, Varadarajan could sense his communityâs excitement leading up to the 2012 championship, as even the students in his elementary school buzzed about how the Giants might win the Super Bowl. He religiously followed the team and the NFL, and in his senior year of high school, he wanted to learn more about what was happening on the field.Ìę
âIâve been watching football for as long as I can remember. I started digging into the schemes and the player techniques in high school. I was watching coaching clinics and game film on my own time just to learn as much as I possibly could about the game,â Varadarajan said.Ìę
At șĂÉ«ÏÈÉúTV, Varadarajan found his place studying statistics and machine learning in the Dietrich College of Humanities and Social Sciences(opens in new window).Ìę
Varadarajan set out to explore his interest in the world of sports analytics, and during Orientation Week, learned about statistician and the Carnegie Mellon Sports Analytics Center (CMSAC).Ìę
Yurko, CMSACâs director and an assistant teaching professor in the Department of Statistics & Data Science(opens in new window), has been a driving force behind CMUâs continued success at the annual NFL Big Data Bowl. Heâs guided multiple projects for the contest since its inception, including two from statistics doctoral student Quang Nguyen that were named finalists in 2023 and 2024. Nguyen and Yurko were also semifinalists for their submission this year.Ìę
âAbhi is a football fanatic,â Yurko said. âHis project looked to objectively quantify these concepts of âstuntsâ and âdisguisesâ using modern tracking data. And he found some interesting relationships there.â
Using positional data from sensors worn by each player on the field during the first half of the 2022 NFL season, Varadarajan tracked how successful teams were at disguising defensive pressure and using stunts (when defensive linemen switch roles).
âTeams tend to either disguise a lot, or have one player whoâs great at winning in isolation,â Varadarajan said. âIf teams donât disguise their pressures, they arenât going to get pressure without a key rusher. If you donât have that talent, you are forced to allocate more resources to causing confusion in order to get pressure.â
A football fanatic
In his pursuit of football knowledge, Varadarajan didnât stop once he found the Sports Analytics Center. This fall, he joined the as a manager to get closer to the game.Ìę
In the role, Varadarajan took on an equivalent time commitment to that of a student-athlete. He filmed games for use in post-game review by the coaching staff, helped to set up the field for practice and games, and maintained equipment. And though he was paid for his time, the real value came from insight gained.
âItâs helped him to be around football, and see the game every day,â said Sam Turner, equipment manager for the Tartans. âWhenever coaches come into the equipment room, Iâd see Abhi try to pick their brains about schemes, and coaches would take him over to the white board to offer their knowledge about anything he wanted to learn."
Varadarajan is also an officer in CMUâs Sports Analytics Club, a student-run sports statistics group that keeps the conversation going outside of class. Like in a chess match â or a pre-snap disguise â heâs setting up a long-term position for success.
âIâd really like to work in a teamâs front office, helping to win games every week,â he said.Ìę

Unscientific Super Bowl picks from professional data scientists, a Tartan football coach and a writer
Who will win Super Bowl LIX, the Kansas City Chiefs or the Philadelphia Eagles?Â
"I am not going to pick against Patrick Mahomes. I just canât do it." â Ron Yurko, CMSACâs director and an assistant teaching professor.
"I am going Chiefs, in another heartbreaker, 27-21." â Ryan Larsen, CMU head football coach.Ìę
"I think Kansas City will win. They are destined for the three-peat." â Quang Nguyen, third-year CMU statistics Ph.D. candidate.
"I find it pretty hard to pick against the Chiefs at this point, because of how well the defense has played, 28-24." â Abhishek Varadarajan, sophomore CMU statistics and machine learning student.
"Chiefs, 27-23. My husband (Giants fan) canât handle cheering for a division rival. This season has been rough already." â Rebecca Nugent, Stephen E. and Joyce Fienberg Professor/ Statistics & Data Science and department head.Ìę
"I'm a Pennsylvania kid at heart. Go birds. Eagles 31-Chiefs 28." â Michael Henninger, writer.
