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.

At 40 years old, LeBron James wants to win, and win now. If he and the Lakers agree to part ways, these teams could make sense.

While they lose key players, the Mavs still have four former No. 1 picks, a rim-running center in Dereck Lively II, another guard in D'Angelo Russell and key wings in Naji Marshall and Max Christie. That's a championship roster.
