I think a team like Atlanta makes quite a bit of sense for him. They'd be scary offensively with him.
It would be a good fit, but I think Bipo is right about the Colts.
They need a running game badly, and they have an elite QB and a team with younger weapons on it than Atlanta. Hilton, Fleener and Allen are going to pieces of that offense for a long time, whereas Julio Jones is the only guy in Atlanta that is going to be there 2 years from now.
Plus, I like Luck much more than Ryan and I think he'd have a better chance of getting to a SB there than Atlanta.
