Nike debuts ad featuring Kaepernick to complement ‘Just Do It’ campaign — it features American flag

Nike rolled out a two-minute video ad featuring former NFL quarterback Colin Kaepernick on Wednesday.

The ad is in conjunction with Kaepernick being the brand's latest face of their "Just Do It" campaign, which launched Monday.

What's in the ad?

Kaepernick shared the video on his Twitter page and captioned it, "Believe in something. Even if it means sacrificing everything. #JustDoIt."

In the video, various acts of athletic heroism are portrayed, including those carried out by NBA superstar LeBron James and tennis star Serena Williams.

The advertisement features a young boy skateboarding and falling off of his board in the process, over and over again, looking discouraged.

A voiceover of Kaepernick says, "If people say you're dreams are crazy, if they laugh and what you think you can do — good. Stay that way.

"Because what non-believers fail to understand is that calling a dream crazy is not an insult; it's a compliment," he continues, as footage of people with disabilities overcome their infirmities to do what some people might consider the impossible plays on.

Kaepernick adds, "Don’t picture yourself wearing [LeBron James'] jersey; picture [LeBron James] wearing yours. Don’t settle for homecoming queen or linebacker: do both. Lose 120 pounds and become an Ironman after beating a brain tumor. Don’t believe you have to be like anybody to be somebody."

The video continues and features James playing basketball, and later attending the dedication of his I Promise School in the Akron, Ohio, area.

"Don't become the best basketball player on the planet," Kaepernick says. "Be bigger than basketball."

The video continues and finally comes full-circle to show Kaepernick himself, standing and staring at an American flag projected onto a nearby building.

"Believe in something," he says, "even if it means sacrificing everything."

The video concludes with Kaepernick walking away, saying, "So don't ask if your dreams are crazy. Ask if they're crazy enough."

The ad will air during Thursday night's telecast of the NFL's season opening game — the Philadelphia Eagles vs the Atlanta Falcons.

Anything else?

Many Nike fans disapproved of Kaepernick being spotlighted by the campaign, and in protest, many of those fans opted to destroy their Nike-branded gear in protest of Nike's pick.

Nike shares closed down 3.2 percent on Tuesday, according to Reuters.

However, according to a Tuesday Business Insider report, Robinhood, a brokerage platform, said that the brand is their 52nd most popular stock in the house, and since the launch of the campaign, holdings have skyrocketed about 300 percent more than they are selling since the previous week.
