We know that daily fantasy players were locked in all day Sunday, but the NFL has one last matchup on the Week 1 slate, and it features many of the games most exciting offensive stars.
This game won’t lack for star power. Underdog will have opportunities for new users to pick higher or lower on these MVP quarterbacks and skill position players, and it’ll also have numerous compelling markets across the Week 2 slate. That one begins with a Thursday night showdown between the Commanders and Packers and is highlighted by Eagles-Chiefs, two teams that have seen each other two of the past three Super Bowls.
