Comparing eras is always quesitonable because of rule changes, ways the game changes over the course of decades, etceteras.
Jordan kind of has a point in terms of the lessened physicality of the game, and of course the expansion of any league will lead to some dilution of talent (which is partly why the Chamberlain-Russell era was so dynamic in its own right, where just about each team had exceedingly dominant players), but times do change. And it's always kind of embarrassing to see yesterday's superstars question the toughness or whatever of the current generation. Soon MJ will start irresponsibly tweeting like Kurt Angle.
Go, Harrison Barnes and Klay Thompson!
