Odom clearly feels Irving is still a force in the NBA -- despite a poor showing with the Celtics in the playoffs.

On the way out of the Fashion Nova event in Hollywood, LO told us a reunion with LeBron James could be the spark that gets Kyrie going again.

Odom also thinks the Lakers should make a run at Anthony Davis -- but that seems unlikely based on the attempted trade drama that went down during the regular season.

As for Kyrie, the guy is immensely talented -- but seemed off during the Celtics playoff series vs. the Milwaukee Bucks ... he just didn't look like himself.

So, could Odom be right? It's a long offseason and Kyrie is clearly unhappy in Boston.

Remember, Kyrie and LeBron weren't always like peas and carrots either -- they won a title together in Cleveland before Irving made it clear he wanted out.

Irving and LeBron later squashed the beef and seem to be cool now.
