I usually don't link to my blog unless it's relevant or cool enough to link to. So far it's been nowhere close, but I think this is something people here will be interested in.
I created a little player pair widget which allows you to filter all lineups by which players were on the floor together (for example, show me all lineups that had Rose, Hinrich, Gibson!), and then it spits out their minutes played together, and the ORating and DRating when they were on the court.
Here's the link with more info. My site's download pages are kinda weird, so if you get lost trying to download it here's the direct link. Instructions are on the blog page if you can't figure out my crappy layout.
