I haven't liked what I had seen from MIL for the 18 months prior to trading for Kuzma. I didn't think they were a contender last season or earlier this season. I have changed my mind since then though.
I thought Kuzma would improve them some because they were so desperate for young legs / speed & athleticism but it has surprised me just how much better the rest of the team looks now that he is on board. Particularly Brook Lopez.
MIL looked so old and slow these past 18 months. B Lopez was slowing down. Giannis was very good defensively but couldn't hide all those flaws. Lillard was a liability. The SG position was often a liability and is still a question mark. And Middleton was a liability at SF.
Just swapping out Middleton for Kuzma has changed from a liability to a strength defensively. But it has not just been a simple swap. Brook Lopez also looks much better defensively because he finally has some protection around him. He has two athletic forwards now in Kuzma and Giannis to shrink the court. B Lopez was always good for MIL in defending in small spaces and around the rim. His problem was in open spaces where he couldn't get help. Giannis and Kuzma have shrunk the space B Lopez has to concentrate on defensively allowing him to play more to his strengths and less to his weaknesses. He has looked a lot better. Not just defensively but offensively too. The offense has been a surprise. Maybe he is just happier now in his improved defensive role but he has looked much sharper and more aggressive on offense for MIL since the trade. Brook is playing his best basketball in 3-4 years.
They also have legit size off the bench in the forward slots too with Taureen Prince and Bobby Portis. Big, long, solid athletes, solid quickness. So when Giannis or Kuzma goes to the bench they can maintain that help for B Lopez much better. Or when Lopez sits and MIL goes small, they have a dynamic defensive frontcourt with a lot of speed while maintaining size & length.
I have been impressed by just how imposing that frontcourt is physically on the defensive end. The are HUGE. Brook Lopez 7-1 260lbs long. Giannis 6-11 (maybe taller) 240lbs. Kuzma 6-9 230lbs. They have been much more effective in protecting their backcourt defensively as well.
---------------------------------
This Bucks team reminds me much more of the squad they had in 2021 (when BOS knocked them out en route to Finals in 7) and 2022 (when they lost to Miami in 1st round) than the team we saw last season in 2023 or earlier this season. They have that defense back to a high enough level once again. As they did when Jrue Holiday was last there.
