This game was a great example of fan bias in the way they analyze the game.

Correct take. The Heat are no longer a team to fear. But still the Bucks are down, why?

This is a highly unusual shot chart we see here. Giannis has his usual group (1) of shots in the paint. And a miss. He has his usual (2) mid range from the right side and his usual miss (3) from 3point range. And then he has 4 misses where he sometimes scores a mid range. And – even more weird- he tried twice from a position he almost never scores!
In fact throughout the entire season last year he hardly ever shot from there and if he did he was terrible.

And zero free throws? No this isn’t incorrect officiating, this is the fact that the Heat have Giannis’ number. Even with little effort they can severely hamper him.

Bucks’ Comeback Ability: This win aligns with Milwaukee’s knack for rallying late, as they’ve now won four of their last five games, including this one against Miami. Their 24-16 record against Eastern Conference teams underscores their strength in these matchups.
Tyler Herro nearly notched a triple-double with close to 40 points, showcasing his scoring ability reminiscent of Devin Booker or Bradley Beal. However, his limited playmaking might have hurt Miami when it mattered most.
Heat’s Road Struggles: Miami, now 26-29, has been inconsistent, with a 4-6 record over their last 10 games. Their defense, ranked seventh in the league allowing 110.7 points per game, couldn’t contain Milwaukee’s 114.1 points-per-game average in the decisive quarter.
Fourth-Quarter Execution: The Bucks’ 35-20 edge in the final frame highlights their ability to flip the script. Miami’s 14.0 made three-pointers per game (slightly above Milwaukee’s 13.9 allowed) likely kept them in it early, but the Bucks adjusted, neutralizing lobs and forcing tougher shots late. And what about that great comeback? Here in numbers the story:

With the exception of Giannis, Dame and Brook, everyone else shot 100%! That is the way the Bucks got the ring, role players shooting the lights out.
