I am not making stuff up because I never claimed he was a better rebounder.
I misspoke. You claimed he was a "comparable defensive rebounder", which has been debunked by several people here. The point is, you "made that up" based on your subjective memory but have nothing to back it up with.
Except it hasn't been debunked. At similar ages, Asik and Perkins were similar players. Perkins got hurt when he was supposed to go into his prime, and Asik had a career year.
If you want to pretend I'm imagining this, that's not my problem.
Perkins from 07-08 to 09-10: 6319 MP, 21.8 DRB%, 6.7 DRB/36min
Asik for his career: 4735 MP, 27.8 DRB%, 9.0 DRB/36 min
You can say that they were similar players, but you have to admit that Asik was a significantly better rebounder if you want to retain any credibility. For comparison, the gap in defensive rebounding percentage between the two over that period is bigger than the difference in career DRB% for Sullinger and Bass.
I don't have to admit to anything that isn't true. I'm just comparing things that I consider comparable (as opposed to mismatched periods of a players' careers):
Omer Asik (aged 24-26):
4,424 minutes, 8.4 DRB/36, ~26 DR%.
Kendrick Perkins (aged 24-26):
5,149 minutes, 7.2 DRB/36, ~23 DR%.
The difference is not large.
It becomes even more slight if you consider that in the season when they were aged 26 (which is typically the start of a player's prime, give or take) Asik played 50% of the minutes used in this calculation, and Perkins played about 15% of his minutes that year while coming back from major knee surgery.
Perhaps it gets evened out by the fact that Asik was a rookie in 2004 -- but while I can concede Asik is a somewhat better rebounder, I can't in good faith term him "significantly better", all things considered.
