There were plenty of reasons for drama in the Milwaukee Bucks' locker room this season and their lackluster regular season record certainly didn't help matters, but most of the dram could be attributed to one man, who happens to be the Bucks' biggest star, at least for now. 

Giannis Antetokounmpo had a very vocal season, even if he wasn't on the court as often as he would have liked. Antetokounmpo played just 36 games this season, his least in a season ever by at least 25 games, due to a series of injuries that he suffered.

Considering that, it would be shocking to the uninformed that the drama surrounding the Bucks wasn't even really that much to do with Antetokounmpo's injury trouble. 

The real issues stemmed from the possibility that Antetokounmpo would leave the team altogether. 

In the first half of the season, there were near-constant rumors that Antetokounmpo wanted out from the struggling Bucks and was willing to force a trade to get there.

Think pieces and speculations abounded as Antetokounmpo asserted in interviews time and time again that he was frustrated with the Bucks and wanted to play for a contender.

But as the trade deadline came and went, Antetokounmpo stayed put. Not only was there no trade, but Antetokounmpo even posted messages online with vague messages about loyalty, then seemingly affirmed that he wanted to win with Milwaukee.

This "will they, won't they" dynamic was something that Doc Rivers had a front row seat to as head coach of the Bucks this season. 

Rivers parted ways with the Bucks after the last game of the season and has since retired from coaching in the NBA as a whole, which means he's much freer to speak his mind about everything he's witnessed this season. 

“The whole Giannis stuff, it just wasn’t a whole lot of fun. It just wasn’t," Rivers said on the Bill Simmons Podcast. "When you’re around Giannis, and then what you hear out the outside, it was two different worlds…. I don’t think Giannis knows if he wants to stay or not. I also don’t know if the organization knows one way or not either.”

That kind of uncertainty from your star player doesn't bode well for the stability of the organization and there's yet another reason that the Antetokounmpo issue could persist. 

Antetokounmpo has two more seasons left on the three-year, $175 million extension that he signed ahead of this past season, but there's a catch.

The third season of that contract is a player-option worth over $62 million, but based on the Greek star's feelings around the organization at this point, he may force a trade before it even gets to the question of him picking up the option or not..
