According to Connor Letourneau of the SF Chronicle, the Warriors have been "preparing for years to make a bid for [Giannis] Antetokounmpo." (San Francisco Chronicle)
Antetokounmpo is eligible to become an unrestricted free agent at the end of the 2021 season. The Bucks will have the first opportunity to re-sign Antetokounmpo under a new five-year deal that could be worth $254 million, via the super-max extension. The article mentions that the Greek Freak and the Bucks are on "good terms" but there will be no shortage of suitors if the Greek Freak declines his player-option. Should Antetokounmpo opt for free agency, the Bucks will have to determine to whether to trade their franchise player for assets or let him walk. The Warriors would likely have to part with Andrew Wiggins, three first-round draft picks, and additional assets to haul in the all-star forward - but hey, anything is possible if Giannis could be hacked.
