Let's look at what Jerry said about Lebron:
The above one is from when Leborn was with the Cavs...notice the words "greatest athlete", "has a chance to", and "could be"...
Let's move a bit more forward to Lebron the Heat and see what Jerry has to say:
So in this one above he says "Jordan would be a tougher cover than Lebron" and he thinks his old Lakers team from the 70's would beat the Heat. Not a ringing endorsement of Lebron or his team. Sure Jerry goes on to say he's a once in a decade type player and out of this world...but nothing in there is Jerry saying Lebron is better than Mike.
He is this decades poster child for greatness. But like it or not he's a quitter. He quit on his team, not only when he left, but while he was there in uniform. Hell everyone saw it...4th quarter evaporations, playing hot potato with the ball, and disappearing for quarters at a time.
Bottom line is you can go ahead with the insults...I see them and laugh because it lets me know I've already won the debate.
