MILWAUKEE — The idea that Giannis Antetokounmpo is going to wear a different jersey is just … wild. It’s hard to comprehend. It’s just not something that you could imagine if you’ve followed his career in Milwaukee or, in my case, covered him here for most of that time.During the last six months, if you’ve spoken to people in his inner circle, the sentiment has largely been, basically, how the f— did we get here? How did we arrive at a place where the Bucks want to trade their most accomplished player? But here we indeed are: The Bucks are trading the greatest player in franchise history to the Miami Heat after 13 years and 979 games.I’ve covered Antetokounmpo and the Bucks in person since 2015, the last eight for The Athletic. Relatively early in my time around Antetokounmpo, it became apparent that he was fiercely passionate about two things — family and basketball — and he would do just about anything for those two things. As those first few years progressed, I quickly came to describe him — in a complimentary way — as a Kobe Bryant-level lunatic when it came to the game.Funny enough, my first significant one-on-one interview with Antetokounmpo came on Feb. 15, 2018, the night he was leaving the Bradley Center to head to his second All-Star Game in Los Angeles. We talked about Kobe.As I walked out of the locker room with Antetokounmpo for this one-on-one interview in 2018, he revealed that the thing he wanted to do most at All-Star Weekend in Los Angeles, outside of competing at a high level, was talk to Kobe and persuade the Lakers legend to work out with him the following summer.By that time, Kobe had already issued Antetokounmpo his MVP challenge and praised Antetokounmpo to former Bucks head coach Jason Kidd following his final game in Milwaukee in 2016. Antetokounmpo wanted the chance to work out with Kobe, but more importantly, talk with him about his mindset and how to be great.As many know by now, Antetokounmpo was successful in the pursuit he laid out to me that night. He talked to Kobe in Los Angeles during All-Star Weekend, and he worked out with Kobe in the summer of 2018.Ultimately, Milwaukee watched him grow up, transforming from an unknown, skinny kid from Greece into a perennial All-Star and two-time league MVP who could put up 50 points in an NBA Finals closeout game while also making unbelievable defensive plays on the other end. And while Antetokounmpo will no longer play for the Bucks, it will be impossible to separate him from the franchise. He may not have ended up being a one-team superstar like Bryant or Dirk Nowitzki, but he will be inextricably linked with Milwaukee for the rest of time.I’ve been one of only a few reporters who have been along for this ride nearly every day, and I’ve seen things I will never forget. I could do this job for 40 more years, and I’m never going to have another moment like the Bucks championship parade. Walking the route alongside the buses as the city flooded the streets and fans pushed up against every barricade. Sneaking into a VIP area to interview the best player in the world, two days after he had just won his first NBA championship, and having him grab my hand to put it on his chest to feel how fast his heart was beating — yeah, I can’t imagine a way I’m ever going to top that.As the franchise icon moves on, here are a few things I’ve learned while being around Giannis over the past decade-plus in Milwaukee.
