It didn't seem unusual to me, so I checked. That's correct for the playoffs. http://www.basketball-reference.com/play-index/tiny.cgi?id=L9ONS In the regular season, Blazers have done it 41 times since Duckworth, including Camby's game 2 weeks ago. Aldridge did it this season, Miles was pretty good before he got injured, and even Outlaw did it! http://www.basketball-reference.com/play-index/tiny.cgi?id=KkTr2
I think it's worth pointing out this post again. The stats do not at all line up with this poster's opinion.
