Nick Foles?

It is not a claim. It is a fact. And I am not going to reveal where I got my info just as I have not done so in the past when giving other info. The reality is, when people ask for sources, it is almost as if they expect some link to be provided. That is just now how it works. The board admins/mods can vouch for me. That said, I am also very comfortable with my comments not being worth a hill of beans.
Just because you say something is a fact, doesn't mean it's a fact. It's just a claim until you provide more than your word that it's a fact. It's a variation on Schrödinger's cat for the rest of us.

Another long time and well respected member of this board knows Foles and his father personally. He's vouched for their character more than once. I've never seen that member make any other claims based on having anonymous "inside sources."

I've seen other claims you've made based on anonymous "inside sources" turn out wrong. If you're going to publicly disparage another human being, you should have the courtesy of being willing to provide something more than just your word when you do it. Otherwise, you're just being a gossip.
