When the Eagles lineup agains the Minnesota Vikings on Sunday at Lincoln Financial Field for the NFC Championship game, it might feel like they are looking in a mirror.
Both teams have an elite defense. Both teams struggle at times to score on offense. Both teams are being led by backup quarterbacks. Neither team was expected to be here.
Despite their similarities, however, the Eagles and Vikings do have some differences, and there are some key matchups each will have to try to exploit to secure a trip to Super Bowl LII.
Here is a position-by-position breakdown, with a look at who has an advantage at different matchups:
