A look at the reaction to Nike's ad with former San Francisco 49ers quarterback Colin Kaepernick

SAN FRANCISCO (KGO) -- As Nike doubles down on its investment in Colin Kaepernick, the player who started the anthem kneeling controversy, there's no shortage of reaction across social media. The apparel company released a commercial that will air on national TV Thursday night during the NFL's regular-season opener.

"So don't ask if your dreams are crazy, ask if they're crazy enough," the ad says.

Nike has released a two minute commercial narrated by former San Francisco 49ers quarterback Colin Kaepernick.

It shows the attainment of impossible dreams - Alphonso Davies, a refugee from Ghana who becomes the hero of the Canadian World Cup team. LeBron James, the child of a teenage mom who becomes a basketball legend and philanthropist. And, everyday people overcoming adversity, including that of "his own," not being employed in the NFL.

Kaepernick's ad features the slogan, "Believe in something, even if it means sacrificing everything."

When asked to comment on the controversy during practice on Wednesday, San Francisco 49ers head coach Kyle Shanahan said, "I don't have a reaction to anything that's happened on this planet the last four days."

It's worth noting Kaepernick never actually played for Shanahan.
