Sean Koerner
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.).
