There's no doubt that SA is one of the best run teams in the league. Hats off to them for maintaining a high level for so many years. They are one of the best drafting teams and have an outstanding overseas scouting system. Both among the top handful, if not the best in the league.
However, let's not pretend they are where WE want to be. Their inability to truly contend the last few years despite solid drafting and overseas player scouting underscore that in the NBA, it takes more than solid drafting... you need to be lucky and daring as well.
Since the KG trade, we've been by far the more likely team to win a title every season since. This season, we have pretty much the same chance of winning the title. About 0%. The previous several years we've always been the team with the better chance to win it all. And that's what its all about.
Going forward, I think the Celtics have the clearer path to their next title. We've got Rondo, Pierce, some decent youngsters/picks and TONS of cap space. I think Danny's plan was to get CP3 and then Howard for the next title runs. Came pretty darn close to pulling that off as well. (How would this team look with Chris Paul and David West on board? I think our chances at DH12 at that point would be pretty good, actually.)
The Spurs are one of the best organizations in the league, but it took the lucky (in our case, extremely unlucky) bounce of the ping pong balls in the Duncan lottery to give them a legit title shot. They are as stuck as anyone right now... very good team, but not a legit title contender.
