LAS VEGAS — A week after actually losing to the public, the sportsbooks bounced back with a winning NFL Week 12, led by the popular Patriots not covering in the marquee Sunday afternoon game against the Cowboys, the 49ers beating the Packers on “Sunday Night Football”, and the Jets crushing the Raiders.

Sportsbooks are used to sweating the Sunday and Monday prime-time games and the big swings they can bring to the bottom line each week — and they needed the Rams +3¹/₂ in the Monday nighter against the surging Ravens — but the big decisions started early this weekend.

The books got off to a fast start in the early kickoffs as the Jets jumped out to a 13-3 halftime lead and added three touchdowns in the third quarter to leave no doubt in a 34-3 upset of the Raiders as 3¹/₂-point home underdogs.

“The Jets’ win was enormous, probably the biggest [early Sunday] decision of the season,” said Jeff Davis, director of trading for the Caesars Palace network of sportsbooks. “We really liked the Jets and someone bet Raiders big early. The Jets aren’t bad. I’m not sure the market has caught up to it yet as they kept betting the Raiders at -3¹/₂ and we resisted going to -4.”

The sportsbooks also won with the Browns routing the Dolphins 41-24 as 10¹/₂-point favorites, the Bills dominating the Broncos 20-3 as four-point home favorites and the Redskins beating the Lions 19-16 as four-point home underdogs.

But it wasn’t all gravy for the sportsbooks. In a game that was flexed from Sunday night to a 1 p.m. ET start, most bettors rejoiced in the Seahawks’ 17-9 victory as 1¹/₂-point favorites at Philadelphia. The books also were on the wrong side of the Buccaneers’ 35-22 upset of the Falcons as Tampa Bay was bet from +5 down to +3¹/₂ by kickoff.

The books were in pretty good shape heading into the late-afternoon games, though Westgate SuperBook director John Murray said the NFL’s schedule-makers don’t do bookmakers any favors with the unbalanced schedule of nine early games and just two late-afternoon games. He said overall handle for the day was down with bettors having only the Jaguars-Titans game opposite the Cowboys-Patriots extravaganza.

Though it ended up as a winner for the SuperBook, Murray questioned the decision-making of Jason Garrett. Trailing by a touchdown, the Dallas coach elected to have Brett Maher kick a 28-yard field goal on fourth-and-7 from the Patriots’ 11-yard line with just 6:04 left in the game. The Patriots held on for the 13-9 victory, though the Cowboys covered as 5¹/₂-point road ’dogs.

“We actually needed New England [to cover],” Davis said. “If the Patriots hadn’t gotten that first down late, they would have kicked the field goal. That was our only loser.”

Caesars and most sportsbooks got healthy with the 49ers’ 37-8 rout in the nightcap with San Francisco covering after closing as three-point home favorites and staying Under the betting total of 48 points.

“San Francisco and the Under was a monster,” Davis said. “There was so much money on the Over and the Packers’ money line. The night game was incredible for us.”

There was one Vegas book that didn’t fare as well with the 49ers — the South Point. Sportsbook director Chris Andrews doesn’t juice their NFL sides at -120, so they took more money on San Francisco at -3 -110 than most other books.

“It was good, not great,“ Andrews said. “We’re in decent shape [for Week 12], though we [needed] the Rams [on Monday night].”
