Let me put a finer point on it for you.
Nick Foles loves playing for the Eagles and the feeling is mutual in Philly Nation. The fan base, probably one of the most passionate in the NFL, loves him, the coaching staff loves him, he's loved in the locker room and maybe most importantly, ownership loves him. He's not leaving all of that to go to a hated rival when there are so many other NFL teams that need a QB. There are no bad feelings here. Almost invariably when a player leaves his team to go to a rival it's because he feels disrespected etc. Not even close to being the case here.
These national NFL beat writers that speculate about Foles signing with Washington or NY are talking out their arse. That ain't happening.
