But if you are going to look at the last 2 playoffs that they were eliminate, specially against the Raptors, he was too predictable that's why the Raptors was able to closed him out.
Then we can put the blame on his teammates for that. Raptors predicted what Giannis can do so what the other 4 on the floor did? Still rely on Giannis in the offense. In the following season, Giannis knows that problem so he began working on being a much unstoppable player on the paint and we have seen him crashing defense even his move is predictable. Other teams can't do anything as even they know Giannis' next move, it's useless as they can't even stop him when attacking the rim. That's what we called improving his main play instead of shifting to other courses such as doing outside shooting or become a better ball handler like Lebron, KD, Leonard, Harden, etc.
The Bucks' problem is not on how Giannis played. The adjustment should be done by his teammates.
His teammates will adjust if the coach will say so, probably the problem is on the coach because he didn't make an adjustment on the game. Giannis is very limited and he is too predictable, so the coach have to make a better plan to get his teammates involved and still make Giannis effective as a player despite of the limited production as he will be doubled as expected.
