"All of a sudden, we have the best backup quarterback in football," Irsay said, per the Indianapolis Star. "I don't think we'd accept a [first-round pick in a trade] for him, we think he's that good."
While the Philadelphia Eagles likely can argue against Irsay's point about backup quarterbacks -- their backup Nick Foles won Super Bowl MVP honors, after all -- Brissett showed flashes during the Colts' 4-12 season in 2017.
Instead, the 2016 third-round pick out of North Carolina State threw for 3,098 yards with 13 touchdowns against seven interceptions. Brissett, who also rushed 63 times for 260 yards and four scores, is under contract through the 2019 season.
Brissett, 25, started off his rookie season as a third-stringer but wound up appearing in three games, starting two, when New England quarterback Tom Brady was serving a four-game suspension and backup Jimmy Garoppolo was injured in Week 2.
