Klay Thompson, Jimmy Butler face off at the Olympics -- in football

Who said there's no American football at the Olympics?

On Sunday, USA men's basketball teammates and NBA stars Klay Thompson and Jimmy Butler showed off their skills on the gridiron in Rio de Janeiro at the Flamengo sports club.

But you'll get two different answers if you're trying to decide who's better.

Team USA is coming off a 119-62 blowout win over China on Saturday in the preliminary round. The Americans will next face Venezuela on Monay.
