Sunday trading preview
- Seahawks to win vs. Titans (38%)
- Fever to win vs. Sky (60%)
Trading on NFL preseason games can be tricky, but this is a solid price on the Super Bowl champs. They aren't going to be going all-out, but some starters should play, and quarterback Sam Darnold should get a series or two. Players like Jaxson Smith-Njigba and Cooper Kupp might not see the field, but rookie running back Jadarian Price could be worth watching for Seattle. Titans fans also should get to see how second-year quarterback Cam Ward, the No. 1 overall pick in last year's NFL Draft, is progressing. The Seahawks lost 17-7 to the Cowboys in their preseason opener, while Tennessee beat the 49ers on the road 19-13 in their first game of the preseason.
The Indiana Fever are looking to bounce back from a 109-102 loss to the New York Liberty on Sunday. And playing on back-to-back days means Indiana stars like Caitlin Clark and Kelsey Mitchell could see a little less time on the court. The good news for the Fever is that the Chicago Sky are really struggling, and the trade of Angel Reese proved to be a bad move for the team. The Fever are fifth in the WNBA overall standings but have lost their past two, while the Sky are 10th but have won their past three. Still, Indiana is by far the more talented team, so we're backing the Fever to win. Trade on Sunday's MLB and WNBA action and more with the Polymarket promo code SPORTSLINE:
