Jordan was an asshole in order to win. Lebron is just an asshole. Try and find a video of MJ flopping. Try and find a video of MJ running a full court length to whine to a ref.
MJ YELLED at people, he reduced them to tears. He didn't pretend he was hurt, didn't pretend he was dehydrated, didn't wink at players after flopping. He just whooped their ass in the game.
Lebron is a different type of asshole. He throws the boys and girls club in front of a heart rip out of Cleveland. He plants excuses as he plays so he doesn't take the blame. (Remember when he "hurt his shoulder" and quit on Cleveland against Boston? No? MJ would never have done that. Whips his jersey off after the loss, and then blames the owner for not surrounding him with good players (newsflash: Lebron wanted those players, just like he wanted Love over Wiggins)
MJ and Bron are two totally different types of assholes. MJ is a selfish asshole who wanted to win at any cost. Bron is a whiny asshole who should be destroying the league, instead he's laying on the floor whining about a stripped ball, a cramp, or a foot issue.
Even Derrick Rose who is missing two knees, has two bad ankles, doesn't complain like Lebron does.
