Backup QBs starting in the Super Bowl is nothing new. Tom Brady won his first in a season where he started the season on the bench. Nick Foles is trying to replicate that, and finally history trends in favor of the underdog Eagles: teams who reached the Super Bowl with a backup QB are 6-2. That might sound surprising, but if a team is good enough to go to the Super Bowl with a quarterback that wasn’t good enough to start (or in some cases, wasn’t deemed good enough but in actuality was), it’s probably a really good team, and the QB probably isn’t too bad himself.
Backup quarterbacks have a pretty good track record in the Super Bowl
