Milwaukee Bucks All-Star Giannis Antetokounmpo is in line for a five-year, $228 million supermax extension. At this point, it's not clear if the Greek star will accept this offer, but the team is gaining confidence that he will, according to a report from ESPN's Brian Windhorst.

Internally, league sources said, the Bucks have gone from cautiously optimistic to cautiously confident in recent weeks that the outcome will be favorable when Antetokounmpo returns from Greece, where he has been since mid-September.

All eyes have been on the Bucks and Antetokounmpo in recent days. The team has made moves to impress their star player, including the acquisition of Jrue Holiday. Still, though, the NBA world awaits Giannis' decision.

It's worth noting that Antetokounmpo does not have to sign a supermax extension this offseason. A five-year, super-max deal with the same terms will still be available for him during the 2021 free agency period. It may behoove him to sign now, though, as it's not clear how the NBA's salary cap will be affected by the 2020 coronavirus outbreak in the coming seasons.

Giannis and the Bucks finished the 2019-20 regular season with the best mark in the league (56-17), earning a No. 1 seed in the Eastern Conference Playoffs. Unfortunately, though, Milwaukee was defeated by a surging Miami Heat team in the second round.

By signing his extension now, Antetokounmpo would squash any doubt as to whether or not the Bucks would be looking to make another playoff push in the coming season. On the other hand, he could wait to evaluate his options for the future.
