This column went 2-1 last week, improving to 5-4 on the season. We cashed Unders in Pats-Jets and Eagles-Bucs, but missed the Over in Saints-Packers. The referees' tendencies figured heavily into our handicapping.

This season, Joe Gibbs (not the Hall of Fame coach, the NFL referee expert who tweets @NFLrefstats1) is collaborating with SportsLine to provide weekly officiating angles. He analyzes the NFL referee assignments from the moment they are released each Tuesday.

Before you make any Week 4 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. Larry tied for 52nd place (out of 1,598 entries) in the 2022 Westgate Las Vegas SuperContest, going 53-34-3 ATS. Those selections formed the basis of his SportsLine NFL best bets, which finished 36-26-1 last season and began this season 6-3 through three weeks.

We can tell you Hartstein and Gibbs are betting Under 40.5 in Buccaneers-Saints, expecting New Orleans to cash its 10th straight Under dating to last season. Shawn Hochuli's crew is calling the NFC South game, and all-time Hochuli is 21-11-1 (66%) to the Under in divisional games.

This season, Hochuli has called 57% of his overall penalties on the offense, including a whopping 44% on offensive lines. "Hochuli ranks second at calling offensive holding penalties this season," Gibbs told SportsLine. "He regularly ranks highly in this category but through three games this year he is averaging 3.33 offensive holding penalties per game."

In his career, Hochuli is 46-35-2 (56%) to the Under, including 2-1 this season.

Hartstein also is sharing key officiating angles in Raiders-Chargers and Seahawks-Giants. You need to see this key referee data before locking in your picks!
