I guess you either have the heart or you don't.

I don't know a lot about basketball but I figure Lebron being as big and athletic as he is is used to having it his way, especially in a sport where you're not allowed to touch him.

A lot of boxers over the years really didn't have that heart, they had all the talent in the world but no heart to tough it out. So when you get a guy in boxing who has world class talent and balls of steel it's a beautiful thing. Guys like Ali, Ray Leonard, and dare I say PBF who fought JLC with a torn rotator cuff.

Some guys have that "put your head down and plough through it" attitude and some guys have the "lay down and die" attitude.
