It's early in the NFL offseason! Anything's possible!

Obviously, Nick Foles is destined to be the next MVP. But who will be the grizzled veteran standing behind him, offering careful, thankless guidance befoer being cast out into the rain? 

You hear that, Donovan? Somebody thinks you don't have the guts to rip that retired jersey off the wall and suit up for the Birds.

That sounds like a challenge, #5.
