This column -- a collaboration with NFL officiating guru Joe Gibbs -- is 54-46-2 (plus 3.33 units) since its debut last season

Gibbs (not the Hall of Fame coach, the NFL referee expert who tweets @NFLrefstats1) teams with SportsLine to deliver three weekly bets. Gibbs dives into the NFL referee assignments the moment they are released each week, unearthing the most relevant betting angles.

Before you make any Week 18 NFL picks or NFL parlays, you need to see what Gibbs and SportsLine senior analyst Larry Hartstein have to say about the officiating crews' tendencies.

A former lead writer for Covers and The Linemakers, Hartstein combines a vast network of Vegas sources with an analytical approach he honed working for Pro Football Focus. Hartstein tied for 52nd place (out of 1,598 entries) in the 2022 Westgate Las Vegas SuperContest, going 53-34-3 ATS. His weekly Vegas contest selections form the basis of his NFL best bets column, which is 99-78-3 (plus 12.18 units) since its inception in 2022.

We can tell you Hartstein and Gibbs are betting Under 40 in Chiefs-Broncos, a game in which Kansas City will rest key starters. Shawn Hochuli is officiating and he's a league-leading 10-4 to the Under this season. In his career, Hochuli is 26-14-1 to the Under in divisional games

Hochuli's crew has called an NFL-high 60% of its overall penalties on the offense. "On all-important third-down plays, Hochuli's crew has called 26.2% of its overall penalties on the defense," Gibbs said. "That's the lowest percentage of any crew in this category."

Hartstein and Gibbs also are sharing key officiating angles in Panthers-Falcons and Chargers-Raiders! You need to see this key referee data before locking in your picks!
