Because the league stipulates that players are not allowed to wear their pre-retirement jersey number, Jordan, who came back at the time, chose the number 45 he wore when he was playing baseball. This is one of the reasons, and the other reason is to commemorate his father.

The player who asked Jordan to switch back to the No. 23 jersey was named Anderson. It was in the 1995 Eastern Conference semifinals. The Bulls faced the Magic. In the first game, in the last minute of the fourth quarter, the Bulls only led by 89. -88 leads by one point. Jordan caught the ball in the backcourt and was intercepted by Anderson. Anderson spat trash talk at Jordan: "No. 45 is not as good as No. 23."

It was Anderson's trash talk that made Jordan stop wearing it. No. 45 jersey. Although NBA regulations at the time did not allow him to wear his jersey number before his retirement, Jordan still wore his No. 23 jersey in subsequent games.

I changed my number without the permission of the league, and the league finally fined me a small amount of money. In this way, every game became the historical swan song of Jordan's No. 45 jersey. Jordan put on the No. 23 jersey, and the once invincible Jordan also returned. In the next three years, Jordan led the Bulls to create a dynasty and complete the Bulls' dream of three consecutive championships in NBA history.

Jordan’s first three consecutive championships:

In the 1990-91 season, Jordan led the Bulls to great success and only lost in the entire playoffs. After two games, Jordan led the Bulls to their first championship.

This includes sweeping the Pistons in the Eastern Conference Finals to avenge one stone, and defeating the Lakers in straight games in the Finals after losing one game at home. Jordan averaged 31.4 points, 6.4 rebounds, and 8.4 assists per game and won the first of his six NBA Finals MVP trophies.

In the 1991-92 season, Jordan averaged 30.1 points per game and won both the regular season MVP and Finals MVP titles for the second consecutive year. In the first round of the playoffs against the Miami Heat, Jordan averaged 45 points per game and led the team to a 3-0 victory. This season Jordan once again led the Chicago Bulls to a championship.

In 1993, Jordan led the Bulls to defeat the New York Knicks led by Patrick Ewing four times in five playoffs. In the crucial fifth game, Jordan had a "triple-double" performance: 29 points, 10 rebounds and 14 assists.

Subsequently, the Bulls passed within six games. In the Finals, Jordan set a record in six games against the Phoenix Suns: he averaged 41.0 points per game and successfully won three consecutive championships.

However, not long after the joy of winning three consecutive championships, Jordan received bad news: his father was murdered. Just before the start of training camp in the new season on October 6, Jordan announced his retirement and was preparing to start his baseball career.

Baseball was the sport that his father inspired him to engage in since he was a child, and Jordan eventually joined the Major League Baseball. In fact, he wasn't very successful on the baseball field.
