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.).

As I wrote up in my Bryson prop, the course will be brutal this week and I think Rahm’s elite approach and around the green play will give him a huge edge here.

3-WAY PARLAY+440
0.15u
“Fever Dream parlay” Sophie Cunningham Under 8.5 Points Sophie is coming off a season-high 24-point game, but if you recall my parlay from that game, I was expecting Clark to rack up a ton of assists (she finished with 14) while Cunningham benefited from some extra scoring opportunities. I’m expecting a bit of a cool down here against an Atlanta defense that ranks 2nd in defensive rating, plays at a slower pace, and forces the most turnovers in the league. Those are all possessions that disappear before a shot can even go up. She’s also shooting 51% from the field this season, well above her career norms, so some regression should be coming there as well. I’m projecting her closer to 7.4 points with around a 57% chance to stay under. Angel Reese Under 12.5 Rebounds Normally pairing a points under with a rebound under from the opposing team creates some anti-correlation concerns, but I think there’s less of that here than people realize. Despite being one of the league’s most dominant rebounders, Reese doesn’t get as many boards on misses at the rim or above-the-break 3s. Cunningham takes 91% of her shots from those two areas, one of the highest rates in the league, so her misses are less likely to end up in Reese’s hands than most players’ misses. Reese does most of her damage on missed free throws, short-range shots, and corner 3s. The Fever provide the 2nd-fewest misses in those areas, making this one of the tougher rebounding matchups she’ll see. The bigger concern for Reese is on the offensive glass. Everyone knows she racks up offensive rebounds around the rim, often off her own misses. Those are absolute killers for a rebound under because she can grab 2-3 rebounds on a single possession and completely change the trajectory of the prop. The good news is Indiana is arguably the best team in the league at preventing offensive rebounds around the rim thanks to Aliyah Boston and Monique Billings doing an excellent job cleaning up those opportunities before Reese can get to them. Under 173.5 A lot of the logic behind the first two plays also points me toward the under. I have this game projected closer to 171. The Fever play at a fast pace and can be turnover prone, which plays directly into Atlanta’s defensive strengths. The Dream force a ton of turnovers, which should reduce overall shot volume, lower rebound opportunities, and potentially force Indiana into a slower style than they’d prefer. Preventing Reese from dominating the offensive glass is also important. Every offensive rebound she doesn’t get is one less second-chance opportunity for Chicago, which naturally suppresses scoring. So while there is some anti-correlation between the three legs on the surface, the underlying matchup data makes me much more comfortable threading the needle here than usual. The sweat guide is pretty simple: When the Fever have the ball, we want turnovers. If they do get a shot up, we’d prefer someone other than Sophie taking it. And if Sophie does shoot, we want the miss ending up with someone other than Reese. When the Dream have the ball, we want missed shots, but more importantly we want Boston, Billings, and company keeping Reese off the offensive glass and ending possessions cleanly. I think the path to all three legs cashing is more likely than the +440 price implies.

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.
