As a camera pans to reveal Kaepernick's face, a reflection of a United States flag is visible on the facade of a building behind him.Kaepernick says: "Believe in something, even if it means sacrificing everything."At the start of the ad, Kaepernick says: "If people say your dreams are crazy, if they laugh at what you think you can do, good. Stay that way, because what nonbelievers fail to understand is that calling a dream crazy is not an insult, it's a compliment."The former 49ers quarterback is revealed as the narrator toward the end of the spot.The commercial's universal theme is about athletes pushing for bigger dreams.

He scored a legal victory last week in his grievance against the NFL and its 32 teams when an arbitrator allowed his case to continue to trial. The quarterback claims NFL team owners conspired to keep him out of the league because of his protests. His case hinges on whether owners worked together rather than decided individually to not sign Kaepernick.A similar grievance is still pending by former San Francisco teammate Eric Reid, a Pro Bowl safety who joined in the protests.Kaepernick already had a deal with Nike that was set to expire, but it was renegotiated into a multiyear agreement to make him one of the faces of Nike's 30th anniversary "Just Do It" campaign, according to a person familiar with the situation who spoke on condition of anonymity because details of the detail had not been revealed publicly.The campaign includes video ads and billboards, like one displayed atop a Nike store in downtown San Francisco on Wednesday.Nike also will create an apparel line for Kaepernick, including a signature shoe, and contribute to his Know Your Rights charity, the person said. The deal puts Kaepernick in the top bracket of NFL players with Nike.The endorsement deal between Nike and Kaepernick prompted a flood of debate Tuesday. It was a trending topic on Twitter and other social networks, with some fans urging a boycott of the company's clothes and sneakers — even burning and cutting out the signature swoosh logos on their gear."I stand for anybody that believes in change. I stand for anybody that believes in a positive attitude," LeBron James said Tuesday night at a Nike fashion show and awards ceremony in New York. "I stand with Nike, every day, all day."Nike also provides all NFL teams with game day uniforms and sideline apparel San Francisco 49ers Hoodie , a partnership that was extended in March to run through 2028.President Donald Trump, a frequent critic of protesting NFL players, tweeted Wednesday that Nike is getting "killed" over the endorsement deal."Nike is getting absolutely killed with anger and boycotts," Trump tweeted. "I wonder if they had any idea that it would be this way? As far as the NFL is concerned, I just find it hard to watch, and always will, until they stand for the FLAG!"The College of the Ozarks, a private Christian school in Point Lookout, Missouri, that competes in sports at the NAIA level, said it will remove all uniforms purchased from Nike that contain the brand's logo.Last year, the college added a stipulation to competition contracts, saying it would walk away from any game where the opposing team takes a knee, sits or turns its back on the flag or anthem."If Nike is ashamed of America Customized San Francisco 49ers Jerseys , we are ashamed of them," College of the Ozarks President Jerry C. Davis said in a statement. "We also believe that those who know what sacrifice is all about are more likely to be wearing a military uniform than an athletic uniform,"AP Business Writer Mae Anderson in New York contributed to this report. The San Francisco 49ers are set to take on the Arizona Cardinals Sunday and are still dealing with numerous roster issues. One thing that will not be happening is the now-anticipated habit of playing musical chairs with the roster. The team has not announced any last-minute roster transactions in lieu of the deadline. The team has until 1:00 PST to waive, promote, and sign players to the roster in anticipation of Sunday’s game. Last week, the duck-duck-goose at quarterback began with the team waiving Tom Savage just days after signing him to the squad. The team brought him back after the game, but that’s how the game is played with the roster and keeping things within the parameters set by the league. At this point, it looks like the 49ers didn’t have any pressing movement to make with players and are sticking to what they have available for Sunday. I was wondering if there would be a roster move in anticipation of Pierre Gar莽on being doubtful, but it looks like the team is going to roll with the young wide receivers in Dante Pettis and Richie James. I half-expected the 49ers to waive Savage again to free up things with other options, but it looks like he’ll be making it through the week as a 49er, though you probably won’t see him on Sunday. Last week they waived him to make room for Tyvis Powell. The 49ers added Savage back when they placed Adrian Colbert on injured reserve but with Richard Sherman and Jimmie Ward looking likely to play on Sunday, they don’t need additional depth for the time being.Well, we hope not.
