NBA free agency has begun, and there are some huge names on the market. There are going to be some big changes that have a massive impact on fantasy basketball. These are the top 10 unrestricted free agents in the market who could impact fantasy basketball.

F LeBron James

James may not be what he once was in his prime, but he's still one of the greatest of all time and would have made an All-NBA team this season if he hit the 65-game threshold. If he changes teams, it will be a massive story in free agency. We expect him to stay with the Los Angeles Lakers, but he could decide to go elsewhere if he doesn't like what their front office is doing.

G James Harden

Harden is expected to return to the Cleveland Cavaliers for next season, but he could test the market. Loyalty has never been one of Harden's strengths, so it's tough to trust that he's going to just re-up with the Cavs.
