Sean Koerner's Picks

Today
Shaheed has struggled to make much of an impact in Seattle’s passing attack since being traded midseason by the Saints. In New Orleans, he operated as the clear No. 2 WR behind Chris Olave. In Seattle, he’s typically been the No. 3 WR behind JSN and Cooper Kupp. JSN commands a massive target share, which has capped Shaheed’s upside in this offense, and Shaheed has also been running routes on only about 65% of dropbacks most weeks. With backup TE Elijah Arroyo returning this week and Seattle dealing with multiple injuries at LT, I could see them using more 2TE or heavier personnel looks, which is when Shaheed tends to come off the field. Backup RB Zach Charbonnet is also out, which could lead to Seattle designing a few more rush attempts for Shaheed, as he’s usually good for 1–2 carries per game. Shaheed has a wide range of outcomes, as he can clear this number with a single catch and could easily go for 80+ yards if he breaks a long one. That’s always the risk when fading such an explosive player. But he now has as many return TDs (2) over the last four games as he does receptions (2), and we’ve been seeing him hit his floor at a much higher rate recently. I’m projecting his median closer to 17.5 yards, with around a 62% chance he stays under 24.5. If he does clear this, it’ll likely be by a lot. That’s why I’m much more comfortable fading him in this market, where his median outcome is much lower. When I invest in Shaheed overs, I usually prefer his alt yardage lines. Shaheed has been one of my favorite players over the years because he often comes through when I’m on his over(s), but this is probably the first time I’ve actually faded him. Based on his recent usage, that’s where I think the play is. He can still make impact plays in the run or return game, just hopefully not in the passing game.

If you remove Week 4, where he left the game early, Lawrence has only cleared this number in 6 of 16 games this season. He’s also been fairly opponent-dependent. He’s cleared this in 4 of 8 matchups against teams that rank in the top half of the league in tackle opportunities for EDGE rushers, but only 2 of 8 against teams that rank in the bottom half. The Rams rank dead last in that metric, and by a fairly wide margin. There are a few reasons for that. Matthew Stafford is tough to sack, having been sacked just 23 times, and he rarely scrambles. Most of his dropbacks end in pass attempts, which are the plays with the lowest chance of an edge rusher mixing in on a tackle. The Rams also use a lot of heavy personnel, sometimes with three tight ends on the field, which can crowd the line of scrimmage and allow other positions to mix in more. Both Blake Corum and Kyren Williams run inside at a very high rate, which funnels tackles toward the interior defensive line, and both rank top three in success rate, so not many of their runs get stuffed for minimal gains, which is where EDGE rushers tend to show up more often. As a result, the Rams tend to funnel tackles to corners and safeties. Sure enough, Lawrence has had a 2-tackle game and a 9-tackle game against the Rams. That 9-tackle outburst was by far his highest total in a game this season. Those types of things can happen in tackle markets, especially when a player is mixing in on a lot of 4–5 yard runs like he did against Kyren Williams and Blake Corum. Tackles, like every stat, come with game-to-game variance based on opportunity. This will be Lawrence’s third matchup against the Rams, and given how few tackle opportunities they typically provide to EDGE rushers, I’m expecting his tackle rate to come back down to earth here. I’m hoping that 9-tackle game was simply an outlier, both for Lawrence and for the Rams allowing an opposing EDGE rusher to nearly reach double-digit tackles. I’m projecting him closer to 3.1 tackles, with around a 63% chance he stays under 3.5.

Running this back after it lost by 0.5 last week, with the final dagger being the 32-yard catch by Boutte against Derek Stingley in coverage on a great throw by Maye. The same logic remains from last week. While I do expect the Maye–Boutte connection to continue operating above a league-average catch rate on downfield passes, he’s still due for at least some regression after posting a league-high +21% catch rate over expected, according to NextGenStats. There’s also a decent chance he lines up across from shutdown corner Pat Surtain II, and the two have exchanged some public comments that at least qualify as mild bulletin-board material. Even if it stays tame, that matchup alone could make it tougher for Boutte to draw targets. On top of that, Mack Hollins has a decent chance to return this week. His return shouldn’t impact Boutte’s playing time much, but it could siphon off some of the downfield targets Boutte has seen at a higher rate since Hollins went down. Diggs and Henry are also coming off down games, and I’m projecting both to see an uptick in target rate this week, which makes it tougher for Boutte to draw 5 targets again like he did last week. I’m still not interested in fading his yardage prop. When he does haul in passes, he makes them count. But I have him projected closer to 2.2 receptions, with around a 62% chance to stay under 2.5.

Chaisson has cleared this in both playoff games so far, largely because he’s racked up sacks. He had one last week and two against the Chargers in the Wild Card round. However, the Broncos have been the 4th toughest matchup for edge rushers, largely due to Bo Nix being one of the hardest QBs to take down. Denver has allowed the 3rd lowest pressure rate, which is mostly an offensive line stat, as they have one of the better OLs in the league. On top of that, Nix posted the 2nd lowest pressure-to-sack rate on the season, which is much more of a QB-driven metric. Jarrett Stidham is more likely to be around league average in that area, with a career pressure-to-sack rate of 19.6%. My tackle and sack model does factor in that increase in expected sack rate against Stidham compared to Nix, but I’m still expecting this OL to make it difficult to generate consistent pressure. As a result, I’m only projecting Chaisson with around a 40% chance to record a sack here. That’s critical at this number, because he’s only cleared 2.5 tackles in 3 of the 9 games where he failed to get a sack. Even when he does get a sack, it hasn’t guaranteed he clears this number. He’s still stayed under 2.5 in 5 of the 9 games where he recorded a sack. In the two games where he had multiple sacks, he finished with exactly 3 tackles in each. If he had only one sack in those games, he would have stayed under. That really highlights how often Chaisson sits under this number, even in strong sack performances. The reason is simple. He isn’t very involved in run defense, as he’s only mixed in on 7% of run plays with a tackle. That gives him roughly 1.3 projected run tackles. Even if I give him a full sack in the projection, he still comes in under 2.5. He has mixed in on six tackles on receptions all season, but even factoring in the small chance he gets one here, that can easily be offset by him failing to record a sack. All of this leads my tackle model to give Chaisson around a 60% chance to stay under 2.5, and I’m surprised we’re getting this at +119.

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.
