I don't think that they should be humiliated with that lost to the Heat. Miami went on to the finals against the Nuggets, it will be bad if they lost to a team that didn't even reach the finals in the East. And it could be a big lessons for Giannis in that series, and to be fair, he got injured early on that series as well.
Your point is valid. The Miami Heat were underrated in the playoffs; not only did they defeat the Bucks, but they also overcame the Celtics – both formidable teams. In fact, these two teams were considered stronger contenders for the NBA championship compared to the Nuggets. The Nuggets gained strength as the season progressed, especially with Jamal Murray returning to his old form.
As for the Bucks, it's possible they've been somewhat complacent due to their previous championship win. Their early exit from the playoffs could be frustrating for them. They've taken a significant step by replacing their coach, and with a new coach in place, there's potential for change. The Bucks might regain their momentum and return to the Finals. However, consistency and maintaining good health throughout the season will be crucial for their success.
Super underrated actually. Not many believed they could go that far, I guess it was only the hardcore fans of Jimmy Butler and the Miami Heat fans who believed they could do it.
Regarding the Bucks, you are right. They may have played with some ease because they already achieve their goal. They ain't that hungry anymore unlike the Denver Nuggets who are so actively aiming for their first championship. Butler too is desperate to have his first ring and his Finals trophy which is why he didn't try to touch the Conference Finals trophy. He wants more than that, the highest achievement of a player and his team.
This season, I think basketball analysts will do the same, they will be putting the Miami Heat in an underrated place but I bet that hunger for Butler is not done yet. One good run will make him a champion someday or maybe this year.
