Buccaneers vs Bengals odds: Former No. 1 picks collide

In a battle of former No. 1 overall picks and Heisman winners, Baker Mayfield and the Tampa Bay Buccaneers will head to Paycor Stadium to face Joe Burrow and the Cincinnati Bengals on Sunday's afternoon schedule.

Mayfield has had the upper hand in this matchup, boasting a 3-1 record in four head-to-head meetings with Burrow. However, Kalshi gives Cincinnati a 65% win probability as the Bengals look to make it four straight wins over Tampa Bay as a franchise.

Ravens vs Colts odds: Indy's Week 1 blues

Before defeating the Miami Dolphins in Week 1 last year, the Indianapolis Colts had gone 2-12-1 in their previous 15 season openers.

Now they'll face a Baltimore Ravens team beginning a new era under head coach Jesse Minter. Lamar Jackson says he's "absolutely" ready for Week 1 after spending the offseason learning a new offense, and Kalshi gives Baltimore a 64% win probability in Indianapolis.

Cardinals vs Chargers odds: Lopsided line

The Los Angeles Chargers enter Week 1 as one of the biggest favorites on the board, with Kalshi giving Justin Herbert & Co. an 81% win probability against the rebuilding Arizona Cardinals.

Herbert offered a glimpse of what the Chargers' new offense could look like in the preseason finale, connecting with Quentin Johnston for a 65-yard touchdown in Mike McDaniel's system. Now they'll look to carry that explosiveness into a favorable Week 1 matchup.

Prime-time prowess

The John Harbaugh era in Gotham begins on Sunday Night Football when the New York Giants host the Dallas Cowboys. Jaxson Dart will make his first Week 1 start, while Malik Nabers is trending toward being available after missing time during the preseason.

Meanwhile, the Kansas City Chiefs are set to host the Denver Broncos on Monday, Sept. 14, with all eyes on the potential return of Patrick Mahomes as Kansas City opens the season against its AFC West rival.
