I don't get the "grain of salt".
The C's rank 9th in ORtg and 3rd in DRtg (the latter is virtually tied for 2nd).
They are among only five teams that is top 10 in both ORtg and DRtg.
They are 7th in SRS rating.
They are 5th in pythagorean wins (meaning they'v actually been a bit unlucky in close games).
They are 7th in margin of victory.
We are on 'pace' to win 49 games based on our season W/L of .597. But we have been winning at a .750 clip since Jan 13, a span of 24 games. It is not a stretch at this point to anticipate breaking the 50 win barrier, since that would require going 'only' .650 over the remaining games.
The Celtics' standing is very much legit. This is a very, very good team.
The Celts are a good team. I'd rank them behind only the Warriors, Spurs, Thunder, Cavs, Clips.
Top 10 in Offensive Efficiency. Top 5 in Defensive Efficiency. Both of those are much higher than I'd ever have thought they could reach this season.
With all of that said, the Celts don't have a prayer at winning the title, and this group hasn't proven they can win even a single playoff game yet. I reserve my skepticism about their chances as a playoff squad, for the reasons I mentioned earlier in the thread.
So, to me, that feels like a somewhat weak team to be at #6 league-wide, which makes me think it's a bit of a down year for the league overall.
Evantime is absolutely right to say that the "sound logic" that went into the too-low win predictions last summer were wrong, wrong, wrong despite that "sound logic." The "sound logic," at least in my case, has to be judged as a case of excessive optimism for a number of other teams in the playoff hunt and excessive pessimism for the Celts.
I'm OK with that. As a general rule, I prefer to be more skeptical of my home town team and more bullish about other teams, since homer bias tends to cut the other way.
The 538 projections site has the Celtics winning 50 games, the Heat winning 47 and the Hornets behind them at 45 wins. So it's not really all that different from the example you listed from 5 years ago.
I guess that's true, but it seems to me when I think back to those KG years, there were at least 3-4 teams that seemed to have a shot at going all the way to the Finals.
Even more recently, say 2012, you had the Heat, Bulls, Pacers, Celts. This year I really don't think anybody has a hope of stopping Cleveland, and Cleveland doesn't seem like a great team. Maybe it's recency bias / nostalgia at work.
