For context, the 2000 Lakers, boosted significantly via scaling from the duncan-less spurs, posted a psrs of +7.8. Hakeem's Rockets topped that through each of the first three rounds(including a matchup against the mid-dynasty champs).
And then we get to the finals where, by Sansteere's process, Hakeem's Rockets graded out at +6.3. For reference that is a better statistical performance than
-> The 88, 89, or 90 Bulls vs the Pistons(peaking at +5.5)
-> The 2000 Lakers vs the Pacers(+2.3)
-> The 1993 Bulls vs the Suns(+4.4)
-> the 2006 Heat against the Pacers (+3.5)
And that is the worst performance of this run by far facing a much better opponent who elevated significantly in the playoffs:
There's context here both ways.
On one hand, the Bucks best player missed a game and was hobbled throughout.
On the other, the Bulls were near .500 with Jordan in the lineup in 86
Nonetheless we see that Hakeem's Rockets are performing vastly better than everyone here via MOV(as well as picking up the most wins) including two good teams.
While I haven't done the calculations(for some of these teams there is no 4-series srs), given that the Rockets are beating all these teams comfortably on available series to series comparisons(excepting the 1993 Bulls), I would be surprised if they didn't end up grading out as having had a statically better postseason by all the listed teams(with the possible exception of +10 psrs 1993 Chicago) by a comfortable margin. And that is despite facing, not one, but two championship-level opponents, one of whom are largely considered one of the 10 best 1-year teams ever, and the other who was in the midst of a dynasty.
Even by RS SRS they are on par with 89/90 Chicago who by most are considered legitimate contenders(the latter being considered legitimately championship-level by some).
Yet, perhaps as a byproduct of them breaking down the next-year, neither 86 Houston or Hakeem is talked about these teams(or their superstars) the same way. But by the numbers, it seems the Rockets were not simply a one-series wonder. Rather, they were a legitimate threat all playoffs, and perhaps a worthy champion in many other years. Maybe if they'd kept all their peices healthy(and coke-free)in 87 and 88 we'd be talking about this team very differently...
