BBD defense and rebounding are above average, not below average.
Out of a 442 qualifying players, Glen Davis is 130th in rebounds per 48 minutes. He is not above average at rebounding, he's above average at offensive rebounding but defensive rebounds are important too.
I'm curious about the offensive rebounding, even. A large part of BBD's success on that end is due to his hustle and energy. However, isn't a large factor in his offensive rebound rate related to his blocked shots? Shots that are blocked back into his arms are credited as offensive rebounds. Since BBD is blocked on 25% of his shots, I've got to think that that factors into his statistical success in that area.
To be clear, though, I like what BBD has been bringing to the team lately. I just think some of his skills have been trumped up a bit by his most ardent supporters.
That may boost his numbers a bit, but wasn't he the only guy in the league to get more offensive rebounds than defensive rebounds? I think so. It's kind of strange. I wonder if he's extra motivated on that end because he has a chance to get two points afterword.
He actually ended up with slightly more defensive rebounds (104 defensive, 101 offensive).
Looking at the numbers, BBD had 279 shot attempts. 58% of those attempts were from inside, so he took approximately 162 inside shots. Of those, 25% were blocked, or about 40 - 41 shots overall.
Assuming he gets back 33% of those shots (which is probably a bit conservative, but who knows?), that a total of about 13 - 14 extra offensive boards. Those would account for roughly 13% - 14% of his total offensive boards, meaning that the large majority of his boards still come from his hustle, etc. However, I do think these extra blocked shots do effect his offensive rebounding percentage by a slight margin, although not by as much as I initially anticipated.
