This column -- a collaboration with NFL officiating guru Joe Gibbs -- is 47-36 (plus 7.5 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 12 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 92-67-3 (58%, +17.59 units) since its inception in 2022.

We can tell you Hartstein and Gibbs are betting the Vikings -3.5 (-105) at Chicago, in part because Clay Martin is officiating. Divisional home teams are 11-22 ATS with Martin on the whistle, including 1-4 SU and 2-3 ATS this season.

Martin's crew has assessed 58% of its overall penalties on the offense, the third-highest rate. Chicago's offense accounts for 63% of the team's penalties, compared to 58% for Minnesota.

Hartstein and Gibbs also are sharing key officiating angles in 49ers-Packers and Broncos-Raiders. You need to see this key referee data before locking in your picks!
