Yeah, according to the article, it was the homeless man "Doc" that related the story to the press, not Romo. When approached about the story, Romo confirmed it but provided no details. This doesn't seem to be a PR move to me.
As much as I hate the Cowgirls, I do like Romo. He seems like a nice guy and he probably has more humility than most players, coming from Eastern Illinois and not being a highly touted prospect.
Most people hate Romo because he gets an inordinate amount of attention on ESPN and other media outlets, but that is certainly not his fault.
