The SI Betting team is red hot in our best NFL bets, going 8-1 over the past three weeksincluding a perfect 3-0 in Week 8.

There are plenty of exciting matchups this week, including a Monday Night Football clash between the Kansas City Chiefs and Tampa Bay Buccaneers.

NFL betting expert Iain MacMillan reckons an upset is his best bet, while Peter Dewey has a game for Monday night’s game.

Here’s a breakdown of each of the best bets for Week 9.

Odds via DraftKings Sportsbook.

Chicago Bears Moneyline (+102) vs. Arizona Cardinals – Iain MacMillan

It’s time to sell the Arizona Cardinals big. They face a tough test in the Chicago Bears, who boast one of the most elite secondaries in the NFL.

They rank second in the NFL in opponent dropback EPA and sixth in opponent dropback success rate. It might prove to be too much for Kyler Murray.

On the other side of the ball, the Cardinals’ defense has been one of the worst in the league this season, ranking dead last in opponent fielding percentage and 29th in opponent EPA.

The Bears offense struggled against the Commanders last week, but they should be well prepared to bounce back in a big way against this Arizona defense.

Kansas City Chiefs -8.5 (-110) vs. Tampa Bay Buccaneers – Peter Dewey

Kansas City has been an elite team to bet on this season not only as an outright winner, but also against the spread.

The Chiefs are also a significantly better defensive team than the Bucs, which I truly believe will be why they win this game.

Kansas City ranks fifth in the league in yards per play allowed, while the Bucs rank 29th in the same category. It was evident last week that Tampa’s defense couldn’t stop the Falcons enough for Mayfield to win the game, and I expect more of the same against Patrick Mahomes and company.

Without Mike Evans and Chris Godwin, the Bucs just aren’t as explosive on offense to play the shootout style they did through the first six weeks of the season.

I’ll put the points with the Chiefs in their fourth home game of the season.
