Vikings vs. Saints trading preview
The Vikings' defense has carried the team to a 4-0 record, despite offensive struggles. But veteran quarterback Kyler Murray showed better chemistry late in Minnesota's 15-10 win against the Miami Dolphins, connecting with tight end T.J. Hockenson, who finished with a season-best 13 catches for 119 yards and opted to go down on the 1-yard line on a would-be touchdown to run out the clock late in the fourth quarter.
The Saints have had the opposite outcome through four games. New Orleans ranks fourth in passing offense with quarterback Tyler Shough and wide receiver Chris Olave on pace to have career seasons. The Saints defense, however, ranks last among NFL teams in points allowed per game (32.0) and total yards allowed per game (360.3).
The Vikings are trading at $0.50 per share to win by three or more points on the road, while the Saints are trading at $0.51 per share to lose by two or fewer points or win outright, at Polymarket. Trade on NFL games and more with the Polymarket promo code SPORTSLINE:
49ers vs. Seahawks trading preview
The 49ers and Seahawks will battle for first-place in the NFC West Division on Sunday. San Francisco and Seattle split road victories during the 2025 season, with the eventual champion Seahawks winning in overtime at Levi's Stadium and the 49ers winning at Lumen Field.
San Francisco tight end George Kittle leads the team with 244 yards and four touchdowns, while newly acquired veteran receiver Mike Evans has a team-best 17 receptions, along with 213 yards and two touchdowns. Seahawks running back Emanuel Wilson, who signed as a free agent during the offseason, has fared well in the absence of injured starter Zach Charbonnet, recording a team-best 190 yards and one touchdown on 53 rushing attempts.
The Seahawks are currently trading at $0.47 per share to win by four or more points, while the 49ers are trading at $0.54 per share to lose by three or fewer points or win outright, at Polymarket. Trade on NFL games and more with the Polymarket promo code SPORTSLINE:
Ravens vs. Falcons trading preview
The Sunday Night Football matchup will feature two of the NFL's best running backs in Falcons star Bijan Robinson and Ravens standout Derrick Henry. Robinson is second among NFL players in rushing yards with 494, while also ranking second among Falcons players in receptions (14), receiving yards (120) and targets (19), having found the end zone in three of his first four games.
Henry has scored a touchdown in every single game and ranks fourth in rushing yards with 374 on an NFL-most 89 carries. The Ravens will, however, be without two-time NFL MVP Lamar Jackson, who was ruled out due to an ankle injury and will be replaced by backup quarterback Tyler Huntley.
The Falcons are currently trading up to $0.48 per share to win by four or more points, while the Ravens are trading at $0.53 per share to lose by three or fewer points or win outright, at Polymarket. Trade on Falcons vs. Ravens and more with the Polymarket promo code SPORTSLINE:
