“The Celtics keep things quiet. Their big moves, from the then-stunning hiring of Brad Stevens 13 years ago to the Jrue Holiday trade last summer, typically don't leak. They did have some player/team involvement when they made the deal to get Kristaps Porzingis in 2023, so it's not impossible, but that was an outlier.
There are two other stumbling blocks for a Celtics deal:
1. It would potentially require the team to break up the successful duo of Jaylen Brown and Jayson Tatum. Regardless of how quiet a team keeps its talks, there's always fallout with the players involved in them.
2. It would require the Celtics to completely overhaul how they play.
One other issue to keep in mind. The Bucks, if they ultimately make an Antetokounmpo move, might need to involve a third or fourth team to either flip players or asset(s) they acquire or to offload another of their player(s) who could be in the deal.
All of this is painstaking and prone to falling apart. That's unsatisfying for those anxious for action, and likely for Antetokounmpo himself, but it's reality.”
