Both teams come off impressive Week 2 victories, but more than 63 percent of the betting volume was on the visiting Packers, according to the consensus picks data at OddsShark.com.
Those bettors should be wary of the Seahawks, who have been terrific in their limited appearances on MNF.
"In their last five games on Monday Night Football, they have three shutouts and are 4-0-1 ATS, so something happens to Seattle on national TV," OddsShark.com football analyst Jack Randall said in an interview this weekend. "Contrast that with Green Bay's recent 2-5-1 ATS on Mondays."
But the MNF trend ignores two key angles that also favor Seattle. After beating Dallas last week as a home underdog, Seattle is now 14-3-1 ATS in their past 18 home games in the month of September, according to the matchup report details.
And in their last nine games as a home underdog, they are a blistering 8-1 ATS.
"All these trends come together in a single game, which may be a harbinger of things to come or just a bunch of coincidences," said Randall. "But it is something for Packer bettors to be aware of, especially in light of all the underdogs this week."
Indeed, eight dogs won straight up Sunday and two more covered the spread (including the Patriots) for a 10-5 ATS week so far. Kansas City, Tennessee, Cincinnati, Jacksonville, Minnesota, Arizona, Atlanta and Oakland all won outright, busting up tons of parlays and teasers and creating an epic day for sportsbooks.
It's not always a good idea to get in the way of a big trend and it's seldom a good idea to follow the betting public's lead. But, Green Bay should be hitting its stride in Week 3 and not everyone is convinced that Russell Wilson can handle the Packer defensive schemes.
