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.

With the NBA Finals and draft complete, the league's offseason frenzy is taking center stage. Phoenix Suns forward Kevin Durant is headed to the Houston Rockets. Teams around the league are keeping an eye on two-time MVP Giannis Antetokounmpo and his future with the Milwaukee Bucks.
