This column -- a collaboration with NFL officiating guru Joe Gibbs -- is 44-28 (plus 13.3 units) since its debut last season. That includes a 7-5 record this year. 

Gibbs (not the Hall of Fame coach, the NFL referee expert who tweets @NFLrefstats1) is working with SportsLine again to deliver three weekly bets. Gibbs dives into the NFL referee assignments the moment they are released each week. Before you make any Week 6 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 contest selections form the basis of his NFL best bets column, which is 84-57-3 (59.6%, +20.90 units) since its inception in 2022.

We can tell you Hartstein and Gibbs are betting Cardinals-Packers Over 47 (Caesars), in part because Alex Kemp is officiating.

Kemp is 56-45-1 (56%) to the Over in his career and 2-2 this season. Kemp's crews are calling a below-average 46.5% of overall penalties on the offense. Moreover, Kemp ranks No. 1 in calling defensive holding and defensive pass interference.

Hartstein and Gibbs also are sharing key officiating angles in Browns-Eagles and Colts-Titans! You need to see this key referee data before locking in your picks!
