Rodman is funny, because by statistical measures, his rebounds are really the only thing that separate him. But he defended 1-5 in his prime, and 3-5 in his Bulls years. If you look at the hall of fame from a statistical standpoint, he's an outlier. He could never be a top 2 player on a traditional champion. Even as a 3rd best player, he needed to be next to multiple HOFers.
But it would've seemed very wrong if he were to be left out of the hall. For all his crappiness off the court, he's one of those players it would be hard to think that he got anything less than everything out of his ability.
