Please take this as one man’s opinion, and don’t take it personally, ok?
I think the four “best” teams — which is different than my “favorite” teams — are:
1. Milwaukee
2. Utah
3. Philadelphia
4. Boston
Probably not coincidentally, Shaq, Lebron and Durant would have all been in my top-four draft selections (with Duncan being the other). That said, it’s important to note that those guys didn’t win every year. Shaq only won four titles, and one of those was due to Wade. Lebron has, relative to his talent, stacked teams, and relatively weak era, has “only” won three times.
I say that not to disparage individual players, but to point out that team construction matters more than having the top handful of guys in the league. So why select these three? I think they offer the best combo of elite talent and fit.
But, I could say something nice about every team in this exercise. It’s the first year in just about any of these drafts that almost every single pick is defensible.
