I just dont see how you can say KG is right there with Duncan at this point in both their careers.
I think trying to say which is 'better' than the other becomes almost a matter of taste.
Well, OK, but according to the 'taste' of most head coaches, sportswriters and other NBA analysts, Duncan is a far better player than KG as of right now.
Like PJ said, Duncan was 1st team All-NBA and 2nd team All-Defense. He also finished 7th in MVP voting. KG was not even really on the map for those awards.
So if according to your taste KG is equal, that's obviously OK, but you have to recognize that it is a minority opinion.
Don't really care.
To me, a lot of this whole thread keeps waiving over the obvious. It is silly to compare the teams based on KG vs Duncan, PP vs Manu, Rondo vs Parker and so on using this last season as the comparison basis, considering that outside of KG & PP, none of the principles on the C's were even 'all there' for the whole season.
There can be no real comparison between the Spurs this year and the Celtics this year because the Celtics didn't really HAVE their whole team for anything but about 12 games in the middle of the season, while the Spurs had most of their main rotation for most of the regular season and most importantly now, in the playoffs. The C's didn't have Bradley or the 'good' Jeff Green in the first half and they didn't have Sully or Rondo in the second half. They were basically a crippled roster one way or another all season.
The Spurs were very simply a much better TEAM this year and I don't think that can be questioned.
Comparing how well KG or any individual played between two teams with such radically different fortunes seems dubious at an exacting level. Team effects DO effect how the individuals perform, even elite superstars. And it also most definitely affects how fans / writers / coaches perceive players. So I'm not particularly worried about whether my opinion is 'minority' or not. I detailed the basis for my opinion and I'll stand by it.
The OP's premise, flawed or not, should only be viewed from the hopeful lens of how well the proposed lineups (on either team) might fair if healthy and performing at at least their recent nominal performance ratings. On who we think those players will be next season, if healthy and integrated. Not on how things went during a bizarrely broken season.
Viewed that way, sure, the OPs premise might still not hold water. Or maybe it does. But the criticisms that are based purely on how crappy THIS year went for the C's don't particularly impress me.
