Sean Koerner's Picks

Today
Getting ahead of this one as the weather forecast continues to trend worse. Rain is expected throughout the game (heavy at times), which should encourage both teams to lean more on the run. The Patriots are 2.5-point home favorites, which projects them to lead for ~15% more snaps than they did in 2024. That added positive game script should tilt them further toward the ground game. Maye also scrambled at a very high rate as a rookie, and I expect that tendency to continue in Year 2. Every scramble is one less passing attempt. On the other side, the Raiders should be more run-heavy under Pete Carroll and Chip Kelly after they landed Ashton Jeanty. That further lowers the expected play volume overall, which limits Maye’s path to a high pass-attempt game. I’m projecting this closer to 29.5 attempts, and I expect the market to adjust as the weather angle gets more priced in.

Robinson has made his living as a low-aDOT volume guy, but Russell Wilson isn’t the best fit for that style. Reports have him lining up outside more, which could mean deeper routes and fewer easy targets underneath. That makes his reception line too high if true. Week 1 props are always a crapshoot (we’re working off beat reports, coachspeak, and speculation) so I’m treading carefully. But this is the type of angle worth taking early. If his role does shift, his receiving yards line (35.5) looks too low. I actually show value both ways, which sets up a reverse-correlation angle: Under 4.5 receptions & Over 30+ receiving yards Parlaying that pays +367, and my sims have it closer to +250 as fair. If he goes his usual 8/30/0, so be it. We’ll finally get real data in Week 1 to sharpen from.

McLaurin finally got paid, but he missed most of camp and we’ve seen plenty of top WRs (Chase, Lamb, Aiyuk last year) start slow in that situation. He’s coming off a career year with a 70% catch rate, which was 11.6% over expected, largely fueled by finally having an elite QB in Jayden Daniels under center. However, that level of efficiency is tough to repeat. Now add in more target competition: Deebo Samuel joins the mix, and with Brian Robinson Jr. gone, Austin Ekeler could take on a bigger early-season receiving role out of the backfield. That creates several factors pulling McLaurin’s target share down. I’m projecting him closer to 4.2 receptions, with around a 59% chance to stay under 4.5. He’s still dangerous in receiving yards markets so this isn’t a fade in that market, but his profile makes him another candidate for the “Under receptions, Over yards” style of reverse-correlation parlay I flagged with Wan’Dale if you want to go that route as well.

Liam Coen’s scheme should give a boost to Jacksonville’s backfield, but usage is still unsettled between Travis Etienne, Tank Bigsby, and rookie Bhayshul Tuten. Early signs point to Etienne and Bigsby handling most of the work out of the gate, with Tuten eased in initially. Bigsby projects to handle early-down snaps, which makes his longest rush prop more appealing than trying to pin down volume. The Jaguars are 3.5-point favorites, implying they’ll play with a lead at a ~17% higher rate than last year, which sets up a higher team run rate overall. Even if Bigsby’s touches are capped, it only takes one carry for him to clear this number. The matchup also helps. Carolina’s run defense has been among the league’s worst over the last two seasons, and while healthier and bolstered with new pieces, this is still one of the easiest spots Bigsby will face all year. Carolina allowed 2.09 yards before contact per rush (2nd-highest) last season. That’s dangerous against a runner like Bigsby, who consistently generates after contact as he ranked 3rd in yards after contact per attempt last year. With the setup of better run-blocking lanes plus Bigsby’s ability to turn contact into chunk gains, the conditions are strong for at least one explosive run. I project his median longest rush closer to 13 yards with about a 59% chance of clearing 10.5.

The Buccaneers averaged 4.0 red-zone trips per game last year (3rd-most), but it’s unlikely they repeat a 67% red-zone TD rate (3rd) or 51% 3rd-down conversion rate (1st) and will be without OC Liam Coen, who’s now with the Jaguars. Even a modest regression in those areas should lead to more FG attempts for McLaughlin. He’s been one of the most accurate kickers in the league, hitting 93.6% of his FG attempts over the past two seasons. His range is elite as well as he’s converted 32 of 39 (82%) career kicks from 50+ yards. That kind of trust from coaches typically earns him a few extra long attempts each year. This game is in a dome, further boosting his expected make rate. I project this closer to 1.9 FGs made with around a 57% chance to clear. Not necessarily a mid-season hammer spot, but for Week 1, this is a more straightforward edge than a lot of the market.

Summary

Sean runs the predictive analytics at Action Network. From the in-game win probabilities in the award-winning Action Network app, to the DFS models on FantasyLabs, to the fantasy football rankings across the network. He also churns out fantasy/betting content for the NFL and is co-host for the Fantasy Flex pod and the betting show Convince Me

Sean creates projects for nearly every sport, from the WNBA to MLB to college hoops and everything in between.

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.).

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.
