Good idea on paper, but a lot of the teams are very similar with 20 or so players that are all on 6 or more teams. Everybody is just looking for the best available guys whose defense is in the mid to high 30s. And there's only so many guys who are really good players while not being good defenders.
Bernard King is on 8 or 9 of the 21 teams that are in so far, and about 7 of those are all the 83-84 season.
