Even if he leads the Philadelphia Eagles to a Super Bowl upset against the New England Patriots in Minneapolis on February 4, Nick Foles may still be unknowable.
Is Foles the Foles who led the NFL in passer rating in 2013 for one, lightning-in-a-bottle season under Chip Kelly (remember him?) Or the Foles who meandered around the league over the next few seasons, finding a home in neither Kansas City or Missouri? The Foles who struggled in relief of Carson Wentz when he ended up back at the Eagles in 2017? The Foles who looked competent again against the Atlanta Falcons in the Divisional Round or the machine that dissected the Minnesota Vikings’ defense in the NFC Championship game?
