Ricky Williams says Colin Kaepernick should consider closing the book on his NFL career -- saying bluntly, "If they don't want you, go do something else."
"I'd rather be somewhere I'm celebrated rather than where I'm tolerated," the ex-NFL superstar told TMZ Sports out in Venice, CA.
Williams says he hopes Kaep plays again -- but really thinks the QB needs to focus his energy on life after football.
BTW, he also gives us his best Kaepernick joke ... and it's definitely one a white person probably shouldn't say.
