The Brooklyn Nets are poised to win an NBA championship with or without Kyrie Irving this season ... so says Charles Oakley, who tells TMZ Sports the star's availability won't derail the team's title hopes.
Of course, Irving -- who is not vaccinated -- could miss more than half of the season due to COVID vaccine mandates in NYC and California ... which has folks like Shaq saying the Nets should get rid of him.
Oakley doesn't think KI's absence will be that big of a deal, though .
