In the NBA landscape, things can change quickly overnight. It was just a few days ago that it appeared that the Miami Heat were the legitimate favorites to acquire Giannis Antetokounmpo. All the momentum was in the Miami Heat’s favor, and just like that, poof. Tons of reports linked Miami as the favorite to land Giannis, the two-time MVP, and now many people around the league believe a new threat has emerged. According to reports from The Athletic, Antetokounmpo would be open to signing a long-term extension with the Boston Celtics. If that is true, that dramatically changes the landscape for the Heat and for the NBA as a whole. Boston Can Offer a Better Trade PackageIf the Boston Celtics truly are interested in Antetokounmpo, then the Miami Heat are in trouble. The Celtics can definitely offer a better trade package for Giannis. The Athletic reported that the Celtics could build a deal around Jaylen Brown, and that's a big deal. The key here is that they can either keep him or Milwaukee can potentially reroute Brown to a third team in exchange for additional prospects and draft picks.
