I refuse to use All-Stars as some kind of status symbol.
How many All-Stars did the Jazz have? Did Mike Conley play like an All-Star? The NBA for some reason loves to reward winning teams with multiple All-Star nods. It waters down and cheapens the achievement. A better argument would be All-NBA teams. Chris Paul has made the past two All-NBA second teams (with Dame funny enough).
But I specifically said SUPERSTARS because to me, a superstar is a different caliber than an All-Star. Kyle Kover was an All-Star. Jamaal Magloire was an All-Star. Magic Johnson was an All-Star despite basically being retired. The nod means nothing, or at least very little. It really shouldn't be used as some kind of measuring stick for HOF nods.
I get it what you're saying and "all-stars" aren't a perfect measure (I haven't found a perfect measure), but to me it is a more consistent label than each persons definition of superstar, which can vary greatly. For sure, not every all-star is the same. However, as I've pointed out, it's incredibly rare for a team with only one all-star, who is of below average height to reach the finals. I think it's tough to make a case that the all-star designation is so meaningless when it has a strong correlation with playoff success.
Another reason I like using all-stars and comparing it to playoff success is that all-stars are selected months before the NBA finals, so you can't just say the voting/selection process is based off of the team who already made it far.
Ultimately, there appears to be a simple formula to determine if your team has a realistic chance to make the finals:
1) Multiple All-Stars - Preferrably ones that have above average length for their position and impact the game on both end.
2) If only one All-Star, the player has to be a 1st team/MVP type player, who is above average height.
The Hawks may buck the trend (no pun intended), but I'll always bet the next years finals team will have multiple all-stars and/or an above average height MVP candidate player. You say you refuse to put any value in that label, but I'd guess you would agree that next years finals teams are more likely to have two all-stars than none. So it's not totally meaningless.
