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.).

This line is pretty crazy considering he’s cleared it in 6 of 8 games, and the Bengals are also a plus matchup for him. I’m projecting Bates closer to 6.2 tackles + assists, so I’m also going to add 6+ and 7+ here.

I’m on a much tighter schedule today, so there will be very limited to no pick notes for a lot of my plays. But for every prop, I’ve still done my usual deep dive where I like the number + underlying factors, and I already expect plenty of these lines/prices to move quite a bit after I post them. I still like the underlying factors enough that I’d play them after a pretty decent sized move. This is a tricky one with Hall back and my guy Braelon “Temu Derrick Henry” Allen playing too well to just go back to a limited role. If anything, I expect Hall to dominate the passing-down work while Allen continues mixing in more on early downs and short-yardage situations. That gives Hall a lower rushing-attempt floor here, especially with the Jets playing as road dogs.

Gary tops my “Sack Lunch” rankings with 4.88 expected sacks on the season and just 1 actual sack to show for it. He’s obviously due, and this could be the ultimate get right spot. Gary should see plenty of Jalen Travis, who has allowed 30 pressures, 2nd most in the league. Does that mean Gary is definitely getting a sack? Of course not. But he shouldn’t be +337 either. I have the fair price closer to +200.

2-WAY PARLAY+950

Going to log this as a parlay first, then track both props individually shortly after. Both have a pretty wide range of outcomes, so I like pairing the alt overs, and there’s plenty of correlation here too. Singletary obviously gets a huge boost with Skattebo likely out, but Tyrone Tracy is also on IR, so there’s room for another RB to get a handful of carries. I wouldn’t be shocked if Gregory Desrosiers gets an early chance and potentially rides a hot hand. He showed a ton of juice for the Chargers in preseason, and this is one of those spots where the data can only tell you so much on a guy with 0 career regular season snaps. This is where all that preseason betting/watching can actually pay off because he’s someone I thought could surprise if he ever got a real shot, and now we finally get a market on him lol. On the other side, I’ve been saying McKee was perfect for Lemon, while Cooper would get the sneaky boost if Milton ever got a start. Well, here we are. Milton wants to push the ball downfield, so I could easily see him and Cooper connecting on 1-2 shots here. Love pairing the alt overs first, then I’ll track both main props individually.

Obviously I expect him to bounce back from last week’s early down usage, but I still think this could be closer to a 50/50 split with Washington. And this 49ers run defense is no joke. Fred Warner might be playing at the highest level I’ve ever seen him play, which is saying something, and now they’ve added Buckner with Bosa back as well. Brutal matchup on the ground. I still think using him in the passing game as an extension of the run game makes the most sense here.

Tracking this as a parlay first to slow down the rapid line move(s) incoming. This is a plus matchup for Stukes, but 6.5 is a tad too high Makes sense to pair him with Greenlaw, who is the main play here and someone I’ll ladder up a few rungs. The only game Greenlaw didn’t clear this number was Week 5, when he headbutted Ernest Jones, got ejected, then served a one game suspension. He came back last week and immediately had 12 tackles. I’m projecting him closer to 6.7 tackles, with a ton of upside from there.

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.
