Sean Koerner's Picks

Rhamondre has certainly been on fire over the last four games heading into the Super Bowl, but I think we could see a dip in both his volume and efficiency in the big game. First, let’s talk about volume. The Patriots have won six straight games and went 14–3 in the regular season, and as a result, they’ve played with the lead 62% of the time this season. That’s allowed them to lean on the run at a higher rate due to game script. However, they still ranked 5th in pass rate over expected, so if they ever do get into a trailing script, we could see their designed rush attempt volume to RBs specifically plummet. We also saw TreVeyon Henderson essentially phased out last week, with Rhamondre racking up 25 carries. A lot of that shift likely had to do with the weather and the massive amount of snow we saw in the second half, as the Pats were simply trying to run out the clock and lean on their defense to keep Jarrett Stidham from beating them. As rare 4.5-point underdogs here, I’m projecting the Pats to play with the lead at a 30% lower rate than usual, which is very high for this late in the season. That means I’m projecting their overall dropback rate to go up and their designed rush attempts to go down, with Henderson mixing in closer to his typical role. That leaves Rhamondre projected closer to 13–13.5 rush attempts, making his Under 14.5 rush attempts (current line) very much in play. The reason I’d rather fade his yardage, though, is that I also expect a dip in efficiency. Rhamondre has been great this year, averaging 4.6 yards per carry, but the Pats have had by far the easiest schedule this season. The Seahawks defense ranks 1st in DVOA and will be his toughest matchup to date. Stevenson has led the league with a ridiculous 6.9 yards per carry against stacked boxes. However, Seattle uses a stacked box at the 2nd lowest rate in the league and instead tends to use seven defenders in the box at one of the highest rates. When facing seven defenders in the box, Rhamondre’s efficiency plummets, averaging just 3.1 yards per carry, which ranks 45th out of 48 qualified RBs. He also runs inside the tackles at the 4th highest rate, essentially straight into the teeth of the defense, which will make it tougher for him to rack up explosive runs. If he struggles early, we could also see Henderson mix in more, which would further lower Rhamondre’s volume. I’m projecting him closer to 49.5 rushing yards, with around a 60% chance to stay under 56.5.

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.
