The 2020 Cowboys have quite the quarterbacks room. Kellen Moore is running the offense, and he spent six seasons in the NFL as a quarterback after shattering records in four years as a starter at Boise State. New quarterbacks coach Doug Nussmeier has a rich history of developing quarterbacks, including Marc Bulger, AJ McCarron, Tom Brandstater, Jake Locker, Brian Hoyer, Jeff Smoker, and Will Grier. And now Andy Dalton joins the team after nine seasons as a starter for the Bengals to backup Dak Prescott.
