Jimmy Butler is switching jerseys to the number he wasn't allowed to wear in Chicago

Jimmy Butler is paying homage to the GOAT.

The former Bulls star could never be No. 23 in Chicago because of some guy named Michael Jordan, but now Butler is free in Minnesota.

Butler posted an emotional goodbye to Bulls fans and the city on Instagram Friday afternoon and fans pointed out he also changed his IG bio to read "#23 in minnesota, forever #33 from marquette."

Butler wore No. 21 during his six years with the Bulls since the most iconic jersey number in sports is retired in Chicago.

Considering Butler is probably the Bulls' best player since MJ, it makes sense Butler would want to follow in Jordan's footsteps in terms of jersey number, too.

Butler wore No. 21 with the Bulls to honor his college teammate, Joe Fulce, who he played with at Tyler Junior College. When Fulce later committed to Marquette, he brought Butler with him in Buzz Williams' first year in Milwaukee.

Jimmy Butler is headed to Minnesota to reunite with Tom Thibodeau.

And as the former face of the Bulls packs his bags to join the Timberwolves, Butler took to social media to say goodbye to Chicago and thank the fans for all they've done over the last six years:

Chicago, What can I say?! I truly struggle with the words because you've been so much more than just my home for the last 6 years, you've been my life! You've embraced me like a son and pushed me to get better every day, every season. I can honestly say that I have always been incredibly motivated to succeed; it's just the way I'm built. But I know I owe so much to the person I am now, and to the player that I've become, to you. You always pushed me to never give anything less than my absolute best night in, night out. That's what you expected. That's what you deserved. And, I hope you know that's what I dedicated my life to every time I walked into the facility or stepped on the floor of the United Center. Thank you to the entire Bulls organization and Reinsdorf Family for taking a chance on me in 2011 and for giving me the opportunity to play the sport I love for such a great franchise. I'll never forget the feeling I had when I was drafted and when I played my first minutes. It's an experience that I wouldn't have wanted with any other team and I'm so thankful to you for giving me that opportunity. Chicago, I love you. Thanks for embracing a kid from Tomball like one of your own. On to a new home and a new organization. Thankfully, with some familiar faces! PS... AND PROBABLY MOST IMPORTANT! THANK YOU TO EVERYBODY BEHIND THE ORGANIZATION THAT DO NOT GET THE SHINE THAT THEY DESERVE!! YALL ARE THE REAL ALL-STARS!! - Jimmy G. Buckets (@staceyking21 )

A classy message from Butler that exudes the exact opposite tone of his personal trainer immediately following the Thursday night trade.

Absolutely love that he signed it "Jimmy G. Buckets" at the end, shouting out Stacey King with one of the most unique nicknames in Chicago sports history.
