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.).

Week 1 is always tricky because there is so much uncertainty. That can make it a good time to find value, but it also means the confidence level on any sort of conviction should be lower. We are dealing with a lot of unknowns. That said, this is the exact type of spot where I think the market may be a bit too aggressive in assuming a rookie RB’s full role right away. My overall take on Jadarian Price is pretty nuanced. I’ve been saying ever since Seattle took him in the 1st round that it was a dream landing spot. With Kenneth Walker III gone and Zach Charbonnet likely to miss time early in the season, Price should open his career as the lead back. So this is not me fading Price as a player. I think he’s good. I think he can look excellent as a runner right away. I’m not really interested in fading his rushing yards prop in the 51-yard range, even against a strong Patriots run defense. That is the market where I’m more willing to buy into his talent, draft capital, and likely early-down role. The reception market is where I want to be more cautious. Price is a bit of an unusual 1st-round RB. He only had 295 touches in college at Notre Dame, although a huge reason for that is he was playing behind Jeremiyah Love, one of the best RB prospects we’ve seen in quite some time. Price was very efficient when he did get touches, and I thought he had 2nd-round talent. But he only had 87 pass-blocking snaps in his college career and is still a bit raw in that area. That matters for rookie RBs because pass protection is one of the quickest ways to lose passing-down snaps early in a career. He also didn’t play in the preseason. That may have been due to the lower-body soreness he was dealing with, or Seattle just wanting to protect its starting RB. But I was still a bit surprised they didn’t get him some live reps, especially as a pass blocker. So in his debut, I think we could see Seattle keep his role a bit cleaner. Let him handle early downs, use him in spots where they are more likely to run, and avoid putting too much on his plate in obvious passing situations. My current assumption is that Price inherits more of the Kenneth Walker role, while George Holani handles more of the Charbonnet role, with Emmanuel Wilson also mixing in. That doesn’t mean it has to play out exactly that way, but it’s the framework I’m using for now. I have Sam Darnold dropping back around 36 times, with Price running a route on roughly 35% of those dropbacks. That gets him around 13 routes. From there, I’m giving him around a 14% target rate and a high catch rate, roughly 80-85%, if he is targeted. That gets me around 1.4 receptions, with about a 59% chance to stay under 1.5. And if anything, I think that projection may already be a bit bullish on his true median passing-game role. I don’t want to fade his 8.5-9.5 receiving yards prop nearly as much because he can clear that on one catch. Again, my concern isn’t what Price can do once the ball is in his hands. It’s whether he will be on the field enough in obvious passing situations to earn multiple targets. He also had some fumbling issues in college, which is another thing that could impact his playing time if it flares up early. I’m not trying to overstate that, especially with Seattle’s current depth chart being Holani and Wilson, but it’s another small factor that makes me hesitant to assume a full all-purpose role right away. I won’t be shocked if Price has a couple catches for 10+ yards and this loses. That is always in play with a talented back. But I think the better way to fade him in his debut is by fading his passing-down usage, not his rushing ability. So my stance on Price for Week 1 is pretty simple: bullish on the rushing role, cautious on the receiving role.

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.
