According to Las Vegas traders, the main storyline in Week 4 of the National Football League (NFL) was the underdogs’ performance.

Yesterday’s (Oct. 4) underdogs finished 8-4-2 against the spread (ATS), with five outright upsets, according to OddsTrader.

A developing betting story is the Las Vegas Raiders, now 4-0 ATS. The Raiders were 5-point underdogs at BetMGM going into their game at Allegiant Stadium against the Kansas City Chiefs and lost 30-27.

Of all those upsets, the most telling was the New England Patriots, who, just one week earlier, lost 35-6 to the Jacksonville Jaguars, raising questions about quarterback Drake Maye (who fumbled twice, threw two interceptions, and was pulled in the fourth quarter).

Yesterday (Oct. 4) was a different story, as the Patriots pulled into Buffalo’s shiny new Highmark Stadium to take on the 3-0 Bills and their vaunted offense. 

The Patriots won 29-26. Maye finished 22/37, throwing for 269 yards, three touchdowns, and one interception. Maye had a 97.7 passer rating (RTG) at ESPN, which is good by NFL standards. However, his total quarterback rating (QBR) was 91.0, which is elite. QBR captures things that passing rating doesn’t, measuring a quarterback’s overall contribution to winning. Maye ran for 54 yards on eight carries, taking only one sack.

“A positive day for the book,” said Christian Cipollini , senior trading manager at BetMGM. We heard from Cipollini while the Sunday (Oct. 4) night game between the Carolina Panthers and the Detroit Lions was being played; the Panthers ultimately won 32-26, another upset (Carolina was a three-point underdog going in). Detroit -3 took 80% of BetMGM’s handle as of Friday.

“The Titans and the Dolphins both covering was helpful and the Bills losing broke up many of the common big favorite parlay bets,” he added.
