A player who wins Super Bowl MVP honors doesn't often find himself on a different team the next season.
It has happened before but not recently. The last quarterback to lead his team to a championship and sign elsewhere in the following free-agency period was Trent Dilfer, who won Super Bowl XXXV with the Baltimore Ravens and then joined the Seattle Seahawks in 2001. The Ravens actually got rid of both of their quarterbacks after the 2000 season, additionally cutting Tony Banks, who was benched in favor of Dilfer.
Nick Foles faces a uncommon situation this offseason.
