Rivers is terrible. The 08 team would have won no matter who was at the helm. We were stacked. Look at what Pop has done with the spurs in a similar circumstances with a aging
group.
This is great, I can now just slightly update my numbers and have lengthy responses by pasting my responses from a month ago, the last time this came up:
You are either over-valuing the Celtics players, or under-valuing the Spurs players, or both.
Both Duncan and Parker are playing MVP-level basketball this year. Per-36 Duncan is averaging 21 pts, 12 reb, 3 ast, 1 stl and 3.2 blocks. KG is averaging 18 ppg, 9 rpg, 3 apg, 1.4 spg and 1.1 bpg.
Parker is similarly having a career year. His numbers are pretty close to Chris Paul's, particularly on a per-minute basis.
Both have been mentioned in MVP discussions during the year.
http://www.sbnation.com/2013/4/5/4186466/nba-mvp-award-2013-lebron-james-kevin-duranthttp://www.nba.us/mvp-ladder/Duncan and Parker have PERs of 24.7 and 23.5 (6th and 9th in the league). KG and Rondo were at 19.0 and 18.1 (38th and 55th).
When the Celtics were winning 60+ games per year, KG's PER was 25 (in 07-08) and he was an MVP/DPOY candidate. We had Rondo playing well, and both Pierce and Allen playing at All-Star or close to All-Star levels.
What we are seeing now is that our best player(s) are simply not at that elite level any more - but the Spurs' players are. The coaches are the same, but the players are different.
As far as the supporting casts, I think that Pierce and Ginobili are pretty equal, with Pierce having the edge this year in terms of minutes and durability.
But Leonard/Splitter/Green/Blair/etc. are superior to Green/Bradley/Terry/Lee/Sully/etc...without getting into the details, I think Leonard is superior in virtually every aspect of the game), but more important we have no one even remotely close to Splitter in the frontcourt.
But regardless it's the difference at the top that really matters. Given the big difference in terms of the top players, and the overall superiority of Spurs talent everywhere else, the difference in their records is not surprising.
You can argue that it's Doc all you want, but Doc coached a 66-win team to the championship when he had a top-5 talent, another top-20 talent and a decent supporting cast. We have nothing close to that now.
