I really don't buy into the whole remarkable health stuff. Yeah, we didn't have any major injuries to our top players, but who in West (that mattered) did outside of MEM (pretty much everyone) and the Clippers (Blake Griffin in the regular season and playoffs and CP3 in the playoffs).
You can't predict injuries, but certain factors played in our favor. We were the youngest team to make the playoffs. Age, in general, plays a factor in the likely hood of injury and also the recovery time. Of course there are exceptions both ways - young players that are injury prone and old geezers like Kareem and Karl Malone that seem to play forever.
Smaller players are also less injury prone that larger players. Again there are exceptions, but in general smaller players suffer less wear and tear on their lower bodies than big men that carry around an additional 50 - 100 lbs. Our top 4 players in terms of minutes played weighed between 195 and 215 lbs.
Perhaps it's just a coincidence, but the two players in our rotation that missed the most games due to injury were our oldest (Gerald Henderson) and our biggest (Meyers Leonard).
None of that changes much this year. Evan Turner replaces Henderson, but is two years younger. Festus Ezeli is now our biggest player, and we all know his injury history. I think most people are only expecting to get about 60 games at about 17 MPG out of him and we have other bigs that can cover for him if necessary.
When it comes to players that actually matter, GSW was even healthier than we were. Their top three players, in terms of scoring, missed a total of 6 games. Those three players accounted for 58% of their scoring. The rest of their scoring was divided between a whole slew of role players. Losing a role player to injury was no big deal for them as they had plenty of other equally talented role players that could pick up the slack.
Our top three scorers missed 10 games and accounted for 54% of our scoring. Our bench wasn't nearly as deep as theirs. So, losing a role player, hurt us more than them.
OKC's top three scorers missed a combined 16 games and accounted for 58% of their scoring. Their bench wasn't as deep as GSW's but they did have a guy coming off the bench that played in all 82 games and averaged 12.7/8.1.
I already mentioned LAC with one significant injury (plus suspension) during the regular season and two during the playoffs.
You can't really judge SAS as the majority of their DNPs were coach's decision (planned rest days). Besides, they won 67 games. It's not like injuries cost them a ton of wins.
In any case, we are still young and our best players are still smaller than league average. We're not relying on a Sam Bowie, Bill Walton or Greg Oden to take us to the promised land. Sure, a freak injury can strike any player at any time, but that's true for every team in the league - more so for those with older rosters (like DAL and MEM).
