I suppose it depends on a lot of factors including which seasons did you use and what was your competition like?
just going on best cases in an open league your team is probably getting beat on the boards routinely because you are playing 3 guards (effectively) and best Rodman (92-93?) should probably be your 3 not your 4 - Kobe with his tepid efg is probably hogging the ball and taking it out of the hands of the other guys, you don't even see Mike too often in opens and if you pick the wrong one of his seasons his efg ain't that great either
or if your point is that these are all-time greats and why arent they more effective? well, this isn't basketball, it's statistical modelling with a dash of market economics thrown in
