Yu Fei didn't go as hard on the Cavaliers, at least not as hard as he had against the Miami Heat previously.
Because at that time, Wade had a clear intent to challenge him, whereas LeBron was only subtly trying to show off his skills. After a few rounds, Yu Fei seized the opportunity and put on a more impressive performance.
Then, the first timeout of the night came, and the Bucks made a strategic adjustment. George Karl subbed out Kevin Martin and Kwame Brown for Latrell Sprewell and Dikembe Mutombo.
With this change, the worst defender on the Bucks' court became Danny Granger, who was playing the small-ball power forward position.
For the Cavaliers, Mutombo replacing Brown was a significant adjustment that clearly impacted the game.
Because at that time, LeBron was still young. He wasn't yet the player who 20 years later could still average 25 points per game using experience, jack-of-all-trades skills, and a robot-like body.
