James isn't winning a title in Celevland without him ...this year anyway.
Don't count on it. A player like Lebron only need minimal help around him to win a championship. If his stint in Miami is any indication, he can pull it off. Now that he has Kyrie, Varajao, a great potential in Wiggins (why people keep insisting that it'll take 3 to 5 years for him to develop is beyond me), and other solid role players, I wouldn't count him out. If they don't get Love, they can still make other trades.
