The last 2 NBA champions

[cow]

That is a very old stat, and many improvements have been made in box score stats (BPM for example) and we now have access to advanced on/off stats (RPM for example) that do a much better job assessing defense (with a big enough sample).

Based on those stats, the teams are laid out as follows:

Bucks:
Elite Superstar:  Giannis  (higher than Luka in both ratings due to his defense)
#2/3 guy:         Holiday, Middleton
Quality Starter:  Lopez, Devincenzo
Quality Bench:   Portis, Connaughton

Mavs:
Elite Superstar: Luka
#2/3 guy:        KP  (this seems like a stretch, but he was at the bottom of a #3 guy.  Much more solidly here last year)
Quality Starter: DFS, THJ
Quality Bench:  Brunson, Powell

The most glaring thing missing in the Mavs roster here is a true #2.  Using these same stats and looking at free agents that could fit that role:

Kawhi (superstar)
Conley (#2)
Lowry (#2/3 but declining)
Ball (#3)
Collins (#3)

That's it (notice DeRozan is missing from the list).  The most impactful thing we can do this off season, is get one of these guys.

Maxi not listed as a Quality Bench and Powell is.  Color me confused.
