I'd be okay with a 2nd, but I don't see him as better than Keenum. He's a backup who had a great run in 2 playoff games after floundering prior to that. Reich had to redo parts of the offense to fit him.
I see your point. But on the other hand, when you can have Wentz and Foles as your backup, I'd want that. You just won a SB with that combo, and it would be a slap to the fans to trade Foles perhaps unless you can get a haul in return. Foles signed a multi-year deal with Philly, so he can't be too surprised if he's a backup there again.
