The Golden State Warriors have been preparing for years to pursue Giannis Antetokounmpo, according to a source. The Warriors similarly planned for multiple years to pursue Kevin Durant as a free agent in 2016.

Antetokounmpo can sign a supermax extension with the Bucks in 2020, or opt for free agency in 2021.

League sources also believe Antetokounmpo would want to leave the Bucks if he loses confidence in the franchise's capacity to win championships. The Bucks had the NBA's best record when the season was suspended in March.

The Warriors' best chance of acquiring Antetokounmpo would likely come through a trade. 

ESPN’s Ramona Shelburne said on “The Jump” in September that Golden State has “always been the big threat” to the Bucks in the Antetokounmpo sweepstakes.
