To the people who point to the 2011/2012 squads: there's a big difference - we weren't elite defensively in those years. IIRC, we were a top 3 defensive team in every single year from 1999-2008. From 2009-2012, we were outside of the top 5 in every year. Not coincidentally, last year was our first time getting back to the Finals...and we were the 3rd ranked defense. This team is similar to last year's team, but here are the differences:
+ Ginobili is back to playing like 6th Man of the Year
+ Kawhi has improved
+ Green has come into his own as a legitimately good defender, and Pop realizes this now (look at how many minutes Green got when Leonard was out)
+ I'm not sure what to think about Splitter. He started off great, and has been great lately, but I'm still not sure if he's better or worse
+ Replaced Neal with Belinelli, which is a noticeable upgrade
+ Diaw 2.0 > Diaw from last year
+ Mills's emergence as backup PG
- Duncan isn't where he was at last year
- Parker isn't where he was at last year
Overall, we've improved IMO. If Parker/Duncan get into their rhythm come playoff time, this team is going to be a serious threat to any team we come across, including OKC or Houston or whoever else people are nervous about facing. I do believe this is our best squad since 2007, and I'm not saying that strictly based on our regular season record. It has more to do with 2013 being our best team in a while, and my belief that this team is better than last year's team.
At this point, all we can do is hope to remain healthy, and hope every one is clicking come playoff time.
