LeBron is the best player in the game, but he hasn't developed that "go for the kill" instinct yet.
Kobe didn't have it at first either, and it took Jordan 5 or 6 years before he became the bully in the NBA at closing out games.
The problem with LeBron is, he's used to being pampered. My friend and I were talking about LeBron today and after bringing up his "advisors", "friends" and now World Wide Wes, we both came up with the assumption that LeBron probably doesn't even think for himself.
Windy's sentiments today kinda further took that along, as Wes (not the poster here

) has had a lot of say in the things LeBron and the Cavs have done in these 7 years. It's really sad in a way.
LeBron is so used to everyone around him telling him how great he is and how he's already the best player.. You're not going to develop the killer attitude like that. You're going to continue to be a pompous ass who wilts away (not statistically, but mentally) in big games and forces the action far too often, or settles for 3's and other bad shots with the game close in hand.
Kobe has faced adversity from the get-go. In LA he struggled at the beginning of his career, trying to find his spot on a team that had some good talent. He also had Shaq which helped him a lot.. Then Phil Jackson came along and we all know Phil doesn't cater to anybody.
Kobe probably got into it a few times with Phil, but Phil flashed his 6 NBA Finals rings in Kobe's face and said "If you want some of these, you'll listen to me." Lebron has NEVER had anybody like that, EXCEPT Coach K, whom LeBron played his most complete game under in the olympics. I don't think he's ever respected Mike Brown because he can go up to Mike and say "What do you have?" or "Where's your NBA career?"...
That is why I think LeBrons growth has stunted (again, not stat wise, but mentally in terms of that killer instinct".
This is all my take, as a fan of the game and a fan of the Cavs. I've watched LeBron for 7 years. I've NEVER seen a player so good at just about every facet of the game.. Sadly, LeBron is always focused on the game. It seems to me he's more willing to be a business man first, entertainer 2nd, and bball player 3rd.
He's got a big part in a basketball comedy that is being filmed this summer. I think he's helping directing and playing a role? Either way, is this the shit he should be doing at this point? I mean, Mike did Space Jam, but Mike had rings.
