Lo and behold, the 2011 Cavaliers are indeed on the list.
Notice how much harder this feat is to pull off now than in the NBA's early days, simply because the league has expanded so much. In the late 1950s, with an 8-team league, "top-6 teams" almost overlapped with "last-place teams". But the 2011 Cavs are the first team to do it in the 30-team era, and just the second in the last 25 seasons. So even in what has been a miserable season for Cleveland, they can take credit for this positive -- and rare -- accomplishment.
Pretty interesting data.
