Mark Grace wore the numbers 28, and 17 during his rookie season with the Chicago Cubs in 1988, and wore the number 17 the rest of his career.
According to http://www.cubsbythenumbers.com/cubs-all-time.html, no Cubs player has worn jersey number 66.
There is no player currently wearing number 17. The last player on the Chicago Bulls to wear number 17 was Ricky Blanton in 1993.
Since Ryan Dempster joined the Cubs in 2004 he has worn #46.
In 1973, jersey number 42 for the Chicago Cubs was worn by pitcher Dick Selma. Jersey number 15 was worn by infielder and outfielder, Bobby Murcer. Both players contributed to the team's efforts during that season.
Currently, Mark McGwire.
As of my last knowledge update in October 2023, number 32 on the Chicago Cubs is worn by pitcher Marcus Stroman. He joined the Cubs prior to the 2022 season and has been a key player for the team since then. For the most current information, please check the latest Cubs roster or news updates.

The Cubs have retired the number of two of their best pitchers. No. 31 was worn by Fergie Jenkins and Greg Maddux. Maddux won his first Cy Young award in 1992 with the Cubs. Jenkins won the Cy Young in 1971. They are considered two of the Cubs best pitchers.
Mark McGwire. Other than that I don't know.
Manny Trillo, one of my favorite Cubs, wore it both times he played for them.
Not many Mavericks have worn #24. To date, only Mark Aguirre, Hubert Davis, Jim Jackson, and Pavel Podkolzin have won that number in Dallas uniforms.
