Reminder: this is total line-up data for each pair of big men on the Kings. I created a cut-off point of 50 defensive rebound opportunities, which gives us 16 duos, new and old. For example, lineups featuring Spencer Hawes and Jason Thompson rebounded 586 of 835 opportunities on defense. League average defensive rebounding percentage is 73.7 percent. Note that the table is sorted by opportunities, not rebound percentage.
NOTE: There may be some inconsistencies in the total data -- the totals from BV don't quite match up with other sources. (I have a feeling "team rebounds" are the culprit.) But assuming the numbers are consistently inconsistent, I believe this makes for a good comparison between the units.
I highlighted the two most common duos of late -- Hawes-Carl Landry (the starting frontline), and Thompson-Landry. You will surely note that neither is any good at rebounding the ball defensively. The derided, forsaken Hawes-Thompson pairing is actually quite a bit better.
It still stinks -- and that's the problem: there aren't really any good options here, in terms of defensive rebounding. (Something tells me Hawes-Ime Udoka wouldn't pan out long-term. Call it a hunch.) The team as it stands is destined for defensive rebounding mediocrity, without a rotation augmentation or unbelievable personal growth.
