I don't doubt that he's a first ballot hall of famer. His antics won't change that. But you can't say that him going to a division rival doesn't tarnish his legacy at least a little bit....particularly w/ the Packer fans that supported him all those years. It's like Elway going and playing for the Raiders. Or Marino playing for the Patriots.
I personally think it's hilarious. It's going to make for an interesting year in our division.
