Should Eagles Be Concerned About Foles as Wentz Backup?

Nick Foles is entering his 6th NFL season and his second stint with the Philadelphia Eagles, this year he is expected to serve as the backup Quarterback for 2nd year Starter Carson Wentz.  The problem is Foles has not appeared in any of the team's three preseason games due to issues with his throwing arm and has been limited at the practices he has participated in.  Should the Eagles be concerned heading into the 2017 season?

NFL Network Analyst and 13 year NFL Offensive Lineman Brian Baldinger joined The Sports Bash on Tuesday and gave his perspective on Nick Foles heading into the 2017 season:

"I think any time a player doesn't play you have to be concerned.  If you think that players get better by hanging around practice or going to meetings, they never do, nobody gets better by not playing.  You know it's a new offense for that guy, he's coming from Kansas City where he was there for a little bit, not that much.  It's a new offense with new players, nobody gets any timing if you don't play; look if something would happen to Carson Wentz right now, I don't see how they could feel comfortable with Nick Foles right now.  Your backup Quarterback is expected to finish games and win games; if anything would happen to Carson Wentz in that first or second game and Nick Foles is your backup Quarterback, I would be concerned."
