Gannon developed into a stud under Gruden, earning 3 Pro-Bowls while with Gruden including becoming the first and only player to win back to back Pro-Bowl MVPs.
And the year he was NFL MVP was the same year he tossed a Super Bowl record 5 interceptions with 3 returned for touchdowns.
Gruden made him a great QB, and Callahan didn't change squat, not even the audibles. That's why Tampa Bay was all over Gannon in the Super Bowl.
