I think both Mavs and Wolves take a step down this year.
Mavs will but ultimately it won't matter where they land as Luka can single handedly get them to the playoffs and likely out of the 1st round. They can be a problem for anyone when you look at the weapons around him as well.
The Wolves are going to take a big step back if Ant doesn't continue his ascent to stardom. He's really good but I'd place him on the same tier as Booker as far as stars that can win in the regular season but they need a system tailored to their strengths to go anywhere in the postseason. The Wolves, like the Suns, aren't built to maximize his talents and almost have taken his considerable talents for granted by thinking they can surround him with anyone rather than playing to his strengths.
I'd also put Jayson Tatum in that tier of star and the Critics proved playing to his strengths and covering his weaknesses with the rest of the roster and system. For that they have a new banner to hang.
