Experience & Accolades

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.).

Sean Koerner's Picks

Today
Has yet to miss a kick this year that hasn’t hit a wire/cable. Projecting closer to a 60% chance he gets 2+
172
25
Projecting him closer to 75.5 with around a 59% chance he clears 69.5
255
28
Projecting him closer to 18.5 with around a 60% chance to stay under 21.5
192
23
He’s the ball carrier in their version of the Tush Push and has been incredibly effective with a 89% success rate (highest for any player with at least 5+ carries) + he’s the lead pass catching TE. They let him get a rush TD at the goal-line a few weeks ago and I would expect maybe 1-2 more of those for him over the final several weeks. Still think the market is a bit behind in his sneaky upside in this market right now. Projecting him closer to +180
202
26
He’s stayed under this number 67% of the time this year. Elliss has rushed the passer 131 times this year which tops LBs and takes him out of tackle opps a LB would typically see, plus he’s been good in coverage. Seattle has been a below average matchup for LBs too. Projecting him closer to 7.4 tackles and a 66% chance to stay under 8.5
81
16
Coming off a massive 9 tackle game but that was on 80 snaps against the Bengals which is a great matchup for CBs. Expected to face way less volume here and Pit is terrible for CBs in terms of tackle opps and I’m expecting LB Roquan Smith to get the biggest boost from this matchup. Projecting this closer to 4.1 with around a 61% chance to stay under 4.5
80
15
Bech has had a very disappointing rookie season, but it’s usually not smart to completely write off a 2nd round WR 12 games into their career. I wasn’t expecting Bech to do much up to this point anyway. But with Thornton and Mayer ruled out for this game I’m expecting him to see a massive increase in usage here. Projecting him closer to 25.5 with around a 58% chance to clear 21.5
212
26
After losing his rec yards prop in brutal fashion last week by 0.5 yard, I’m going to stick with the market I think suits him better anyway. When evaluating rookie WRs, it’s always important to look at both talent and landing spot. Tet McMillan and Emeka Egbuka were two of the top WRs of this year’s class and landed in ideal situations to produce right away. Both benefited from trades or injuries that elevated their usage even more. Burden, on the other hand, was a fringe 1st round talent who landed in a very crowded room of pass catchers with limited passing yards to go around. That was always going to make him easy to overlook. I’m not saying he’s the same talent as CeeDee Lamb or JSN, but I’ve pointed out he could have a similar career arc where he starts behind 2+ established WRs, then eventually sees a production jump as injuries happen or the team moves on from someone like DJ Moore. He recently passed Olamide Zaccheus to become the team’s #3 WR, but he has still been topping out around a 60–65% routes-run rate. With Rome Odunze ruled out this week, we could see his first game in a more full-time role, potentially 80%+ routes, and with one fewer high-end WR to compete for targets with. This is the type of stretch where I’m expecting Burden to show more of a true breakout. The matchup is brutal, but the Bears may be forced to throw at a higher rate, and they clearly want to find ways to get the ball in his hands, as we saw with the pop-pass look last week. This is the better market to invest in his upside, and I’m projecting him closer to a 62% chance to clear 3.5 receptions.

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.
