Greg Knapp has coached numerous quarterbacks over his 21-year coaching career, from Hall of Famer Steve Young to Michael Vick, Matt Schaub, Carson Palmer and Peyton Manning.
His current mission is to develop Trevor Siemian and first-round draft pick Paxton Lynch to be the franchise quarterback of the post-Manning era for the Super Bowl champion Denver Broncos.
Manning left the Broncos with his second Super Bowl title and the club's in March. So did Brock Osweiler, who many thought would be Manning's successor, leaving for Houston via free agency a few days later.
