Is that a new thing to just grab your wife's ass in a classy photo? It just looks kind of funny to be all dressed up and formal, and have his hand cup that ass like foreplay.
I don't know about your situation but my wife has the same kind of ass that I can cup with one hand. Personally, I'm not into chicks that need a Bear hug to feel both cheeks if you know what I mean!!!
All kidding aside, their marriage has probably been a huge boon to the Pats. Who knows if he would take a discount the last 3-4 years if his wife wasn't also rich.
