​The Atlanta Falcons are finally back in action for their first regular season game of the Kevin Stefanski era. However, there’s still some uncertainty at quarterback entering their Week 1 matchup against the Pittsburgh Steelers.The Falcons named veteran QB Cooper Rush as the starter, but the team said he was suffering back spasms on Saturday. This has led some to speculate that we could see undrafted rookie Jack Strand take the field during today’s showdown in Pittsburgh.The Steelers were already favored before the Falcons ruled out Tua Tagovailoa and Michael Penix Jr., and the odds have only skewed more towards Pittsburgh since Rush was deemed QB1.
