Villanueva calls out KG

In a recent tweet by Pistons forward Charlie Villanueva, he writes "KG called me a cancer patient, I'm pissed because, u know how many people died from cancer, and he's tossing it like it's a joke." He goes on saying, " KG talks alot of crap, he's prob never been in a fight, I would love to get in a ring with him, I will expose him " . I know this can seem offensive to alot of people. This happned on the court where there is alot of trash talk but why does Villanueva want to throw that out there and then mention he would expose him in a ring? Please dont be offended.
