The Los Angeles Lakers pulled off one of the NBA's most stunning trades, acquiring Luka Dončić from the Dallas Mavericks this past season, signaling a significant shift away from LeBron James as their centerpiece star.

LeBron James' agent, Rich Paul, told ESPN's Dave McMenamin that four teams have already checked in with him about a possible deal.

NBA free agency officially kicked off on Monday evening as the negotiating window opened for eligible players and all teams across the league at 6 p.m. ET. Monday night was relatively quiet, but the first stunners of the new league year came Tuesday morning.
