Experience

Sean is one of the most decorated fantasy analysts in the industry, finishing first in the FantasyPros In-Season Accuracy standings in 2023 – which measures almost all fantasy football analysts on their in-season projections over the course of the season. You can read more about their methodology here. He also won the in-season ranking title in 2015, 2016 and 2017. This past season, he not only finished first overall, but was the No. 1 ranker out of 180+ entrants in running back, wide receiver and kicker rankings. He was top 10 in quarterbacks and tight ends, as well.

His 2023 performance was arguably the best in the contest’s history:

  • It was a record fourth No. 1 finish in the accuracy contest
  • He was the first expert in history to be No. 1 at multiple positions (RB + WR)
  • He was the expert to finish top 10 at every position

Sean started 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 every 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.

Sean began his betting career in college by building sports betting models. He eventually turned into a bookie in college before moving to Vegas to work at Excalibur Sportsbook as a supervisor. He decided to move back to California to begin a career in fantasy sports/betting at RotoHog as a product manager. That was when he began entering his season-long fantasy projections into the FSTA contests and won the award for most accurate season-long NFL & MLB projections 2-3 times each.

He then moved to NY to work for Bloomberg Sports as a product manager and Head of Projections. They were eventually acquired by STATS where he maintained the same role as a product manager. That was when he began entering his weekly NFL rankings into the FantasyPros accuracy contest and won first place 3 years in a row from 2015-2017. He joined Action Network in 2018.

Education

Sean has a BA in Psychology from Long Beach State and took multiple advanced stats classes. He spent most of his 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.).

Kiah Stokes should play around 15-20 minutes tonight, and Golden State didn’t really have a dominant rebounder like this last season, so Burton’s rebound rate, along with everyone else should take a bit of a hit when Stokes is in the game. I’m projecting Burton closer to 4.2 rebounds with around a 59% chance to stay under 4.5.

Sale has been one of the top strikeout artists of this era, with arguably one of the best strikeout pitches of this era in his slider, but both are finally starting to show slight signs of decline in his age-37 season. His overall whiff rate is currently at its lowest point since 2016, while his slider specifically has seen around a 5% drop in whiff rate. He’s also nearly tripled his sinker usage this year, another subtle sign he may not be relying on overpowering hitters quite as much anymore. My expected K model has him closer to a 24.5% K rate so far due to a handful of smaller red flags. Today’s Dodgers lineup is also quietly tougher to strike out toward the bottom of the order than people realize. Guys like Rojas and Espinal are very tough Ks, so even if Sale’s pitch count is running efficiently and he gets to face a couple extra hitters, it doesn’t really raise his ceiling all that much. Fading Sale is never fun and anytime the Dodgers get into a 2-strike count tonight you can find me hyperventilating into a paper bag. But I’m projecting him closer to -135 to stay under 6.5, so getting plus money is a nice bonus.

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.
