Colts at Rams

TV: Sunday, 4:05, CBS (Ian Eagle, Dan Fouts. Evan Washburn)

The matchup: The Colts will open the season without injured QB Andrew Luck.The last time Indianapolis went into a season without its starter, in 2011, the Peyton Manning-less Colts were surprisingly competitive in a three-point loss to the Steelers. These Colts have nowhere near the firepower of the Manning teams and will have to rely on aging RB Frank Gore and a young receiving corps led by T.Y. Hilton. ... Is Rams QB Jared Goff ready to take the first step toward NFL stardom? Or is he the next JaMarcus Russell? Goff has a new weapon in WR Sammy Watkins, who didn’t make much of a preseason impact. Just as important is getting RB Todd Gurley and the ground game back on course after a frustrating 2016 season. The Rams could be without their best player, DT Aaron Donald, who sat out the preseason because of a contract dispute.
