Director Predictive Analytics
20 years
Los Angeles


Sean runs the predictive analytics at Action. From the in-game win probs in the app, to the DFS models on FantasyLabs, to the fantasy football rankings on TAN. He also churns out fantasy/betting content for the NFL and is co-host for the Fantasy Flex pod and the betting show Convince Me. His projections also furl the March Madness Simulator. Sean starting to become obsessed with sports betting & fantasy football ever since his father took him to Las Vegas for his annual fantasy football draft (at 8 years old). Sean started trying to project teams/players ever since and almost ever action/decision he's made since has led him to where he is today. He began betting 20 years ago and began his sports betting/fantasy sports career as soon as he graduated from college in 2007. Prior to joining Action in 2018, he worked for MGM, RotoHog/FastPoint games, Bloomberg Sports, STATS.


Began his betting career in college by building sports betting models, making bets. eventually turned into a bookie in college (maybe leave this part out) before moving to Vegas to work at Excalibur sportsbook as a supervisor. Decided to move back to CA to begin a career in fantasy sports/betting at RotoHog as a product manager. That was when I began entering my season long fantasy projections into the FSTA contests and won the award for most accurate season long NFL & MLB projections 2-3 times each. Then I moved to NY to work for Bloomberg Sports as a product manager and Head of Projections. We were eventually acquired by STATS where I maintained the same role. That was when I began entering my weekly NFL rankings into the FantasyPros accuracy contest and won 1st place 3 years in a row 2015-2017. Joined Action Network in 2018.


BA in Psychology from Long Beach State and took multiple advanced stats classes. Spent most of my time in the library reading stats/sports betting books creating prediction models and using them to bet on various sports (MLB, NFL, NBA, WNBA, etc).

Betting Highlights
Favorite Bet of All-Time
Patrick Mahomes under 30.5 rushing yards for Super Bowl LIV. He had 44 yards going into the final drive. Kneeled down 3 times for -15 yards to drop down to 29 yards and hit the under
Most Heartbreaking Bet
Max bet Jimmy Graham under 23.5 rec yards in the WC playoff game against NO in 2020. He had 6 yards heading into the final drive with the Bears down 3-21. On the final play of the game, Mitch Trubisky finds Graham in the back of the end zone for an insane one handed grab for a 19-yard garbage time TD. Graham finished with 25 yards and I'm still tilted by this. Side note: Stuckey was on this prop with me.
