Who will win in Brazil? Make your picks!

Believe that the USMNT will find success at the 2014 World Cup. "Believe that we will win," as the latest World Cup promo from ESPN — a tribute to the American Outlaws supporters group — urges.

Believe, because US women's national team stars Abby Wambach and Hope Solo tell you to. Believe, because Jimmy Kimmel, Whoopi Goldberg, Jon Hamm, and Ice Cube tell you to. Believe, because NBA and NFL stars Rajon Rondo and Cam Newton tell you to. 

And if that's not enough for you, believe because Mad Men's Don Draper — also known as Jon Hamm — pitched it to you.
