IMO: the Eagles are going to run about the same Offense with Nick Foles as the #1 QB.
Originally a third-round draft choice (88th overall) by the Eagles in the 2012 NFL Draft,
2014 - PHILADELPHIA EAGLES (8/8)
Posted his third career 400+ yard performance (411) while setting career highs with 62 attempts and 36 completions at Ari. (10/26/14)
The Eagles’ all-time leader in passer rating (94.2), Foles has completed 776-of-1,285 (60.4%) attempts for 9,215 yards, 56 TDs and an 88.2 passer rating in 42 career games (36 starts).

2016: In Kansas City and a reunion with head coach Andy Reid and a familiar system,
2016 - KANSAS CITY CHIEFS (3/1)
Saw action in three games (one start) as a back-up to QB Alex Smith.
Completed 36-of-55 (65.5%) attempts for 410 yards, 3 TDs, 0 INTs and a 105.9 passer rating.
He played substantially in two games that season and threw three touchdowns and zero interceptions and looked good enough that the Eagles made a considerable investment to bring Foles back to Philadelphia as insurance for Wentz.

Backup QB: Nate Sudfeld ( 6' 5" / 227 )- an original sixth-round pick in 2016, spent his rookie season in Washington on the practice squad with Kirk Cousins and Colt McCoy on the active roster. After being released at the end of this year's preseason, he chose not to re-sign with the Redskins' practice squad and joined the Eagles' one instead.
Two months later, the Eagles promoted Sudfeld to the active roster after another team wanted to sign him.
