McKee's three-year preparation and spring outplay of Dalton suggest QB2 role is his to lose.

Tanner McKee has quietly prepared as a backup quarterback for the Eagles for three full years, diligently preparing as if he's the starter. When given opportunities—with the exception of one game last season during which he played with the second-team offensive line and backups at skill positions—he has mostly looked the part of a player who could earn a starting job at some point, even if with another team. Despite his continued progression as a pro quarterback, he was competing for the QB2 job this spring with a 38-year-old Andy Dalton, acquired via a seventh-round pick. McKee pretty clearly outplayed Dalton during spring media-attended practices.
