Believe in something, even if it means sacrificing everything. #JustDoIt

The brand really took a risk with this.

People are freaking out over Nike's decision to feature Colin Kaepernick in their newest ad campaign, and one of those people is tennis legend Serena Williams, who is also featured in the series of promos.

"Believe in something, even if means sacrificing everything," reads the words scrolled across a black-and-white photo of the football player's face.

"Especially proud to be a part of the Nike family today," she wrote. "It's only a crazy dream until you do it," hers reads, along with a childhood photo of herself practicing on the court. Powerful!

Kaepernick was the first NFL star to kneel during the National Anthem in protest of racism and police brutality, and it got him dropped from the game. None of the 32 teams in the US wanted to sign him for fear of backlash, but he felt it was an important enough issue to sacrifice his career over.

A lot of fans are pissed, however, because they feel standing for the National Anthem is simply an issue of respect, and therefore there's been a lot of videos posted from people that are burning their shoes and doing other crazy things to show their disapproval.

A little controversy never hurt anybody.
