I don't have the exact numbers from before the first game against Minny, but IIRC, Portland's defensive rating was about 114.8-115.0 and their net rating was around -8.5
I don't really recall what the offensive rating was but I think it was somewhere in the 106-107 range
so I was curious about Portland's numbers in the last 4 games:
Minny #1: def rating 108.0....net rating +14.0 (off rating 122.0)
Minny #2: def rating 98.4....net rating +8.0 (off rating 106.4)
Atlanta: def rating 107.9....net rating +4.0 (off rating 111.9.0)
@ OKC: def rating 112.2....net rating -10.3 (off rating 101.9)
what about the 4 games prior to the B2B Minny games?
Memphis: def rating 121.4....net rating -39.8 (off rating 80.6)
@ Minny #2: def rating 119.9....net rating -23.6 (off rating 96.3)
@ Spurs: def rating 126.1....net rating -13.9 (off rating 112.2)
@ New Orleans: def rating 107.6....net rating +19.3 (off rating 106.4)
obviously, there's a home/road imbalance in the comparison. But the Blazers did catch a huge break and play New Orleans when the Pels were missing 4 starters and their 6th man. The counterweight to that is the Blazers played by far their worst game of the year against Memphis.
and of course, small sample sizes.
Still, it's hard to ignore Portland's improvement when Simons and Ayton didn't play. That's especially true on defense. In the 4 games Simons/Ayton played the quick and dirty def. rating average was 118.8; in the 4 games they didn't it was 106.6 (season mark is 113.5). Now, I doubt even Simons and Ayton fans would say they wouldn't expect Portland's defense to get better without those two guys. But the other side of those expectations would probably be that Portlands's offense would get worse. But it didn't. Portland's season mark in off. rating is 106.4. The Q(uick)&D(irty) average in those 4 games without the pair was 110.6. And, while the season net rating is -7.1, in those 4 games without it was +3.9
of course, I'm obviously biased. I've been pretty open about my disdain for Simons and Ayton as players. I believe they are both empty calorie players carting high usage who tend to subtract more than they add. So this all dovetails neatly into my bias. And as I said, the sample sizes are way small and there's a reverse home/road imbalance. But those number sure do fit into what we've watched
