The guy have the biggest adversary coming into playoffs. Lost his sister, lost his tooth and grinded his way to the ECF with his 5'9" body. He already stated before even the Cavs series that he's hurt but he doesn't want to disclose how severe it is because he might miss games.
You can call him a chucker, defensive liability, etc. But quitter is not one of them.
Cavs fans ain't one to talk about quitting, because Lebron is historically known for quitting on his teams.
