Robinson, Malone, Ewing, Barkley, etc. sounds nice, but who among them is going to guard LeBron? Melo? Durant? Not to mention, you can't play them all at once, which somewhat diminishes that advantage.
The '92 team is more stacked top to bottom, and has fewer glaring holes, but in an actual basketball game where athleticism and match-ups are taken into account, they would have their hands full.
