One guy that gives me some perspective on this is Shaq. The guy has been around forever. There are zero players still around from the draft class after his. There are 3 guys around from the one after that. And KG out of high school is the only one around from the class after that. No wait. Antonio McDyess is also.
Shaq was absolutely dominant for a very very long time and he isn't going to break that many records.
This is just really hard to do
Shaq missed a ton of games though, injury prone his whole career.
I can tell you never actually watched Shaq if you say he has been "injury prone his whole career" (maybe you never even looked it up). Last season was Shaq's 19th season, he had missed only like 2 or so (I'm too lazy to get an actual number but I watched him, so I know it isn't much more than that) playoff games b4 this season b/c of injury (only missed the playoffs 1 of those seasons so that would make 17 playoff appearances not including this one)! He has been injured his last few seasons quite a bit but he played like 78 games only 2 seasons ago and that was b/c he was intentionally held out on some of the Suns b2b games or he would have played in them all! His season with the Cavs was b/c of a freak injury (that Shaq has had 2 times 0.0) BBD caused by stripping the ball and getting Shaq's thumb. Counting on Shaq playing in the playoffs wasn't as huge a gamble as some would say (now that it's over, hindsight is 20/20), going off of Shaq's history of playing in the playoffs, it wasn't as if they put the chips on someone who frequently was out b/c of injury in the playoffs before!
Sorry, but the evidence doesn't back you up:
http://www.basketball-reference.com/players/o/onealsh01.htmlOver the course of his career he's missed about 20% of his teams games. This isn't all that skewwed by him getting older. When he was 23, 24, 25 he only played in 54, 51, 60 games respectively.
Shaq has always been an injury prone player. He hasn't missed full seasons but more often than not he'd miss 15-20 games. He played in the playoffs most years, but that doesn't mean he wasn't injured frequently through out his career.
Compare that to a guy like LeBron who's only missed 29 games total in his career. Shaq racked that up in on season when he was 23.
