It is a little bit sad that Kobe will never win the league MVP award, let alone another ring. He was fortunate enough to come into the league in 1997 and join a team that was already a perenial playoff team. The '97 Lakers starting lineup looked like this.Shaq, Elden Cambell, Eddie Jones, Byron Scott, Nick Van Exel. Kobe was then fortunate enough to win three rings, in three years starting in 2000. Who was the league MVP in 2000? Shaq. Finals MVP in '00, '01, and '02? Shaq. Lakers scoring and rebound leader on all of those teams? Shaq. O'Neal is believed to be the most dominant player of all time by many. 
Seems like a life time ago. Kobe's career field goal percentage is 45%. Dropped to 43% after Shaq  left for Miami.

LeBron on the other hand inherited a team in Cleveland that hadn't been to the  playoffs in seven years. With running mates like Jeff McInnis, Darius Miles, Carlos Boozer and Zydrunas  Ilguaskus. So it took James three years to get this raga-muffin bunch to the playoffs. With a rookie coach at the helm mind you. LeBron is setting rookie playoff marks with each game he plays.
LeBron put up numbers in his rookie season comparable to only Oscar Robertson, and Michael Jordan. His numbers continue to improve every year. What was the knock on Bron when he came into the league? Questionable range and consistency  with the jumper. How about 43% from 3-point range, and 49% overall in his first ever playoff series.Compare that with Kobe's 26% from downtown and 47% overall against the defenseless Suns in his  first round series. Kobe 24.2 per in the playoffs. LeBron 36.4.
What was the knock on LeBron during this regular season. He doesn't step up and take the big shot. He kicks it out to open shooters. Um, not so much in the playoffs. More like steamroll your way to the orange explode strong and dare anyone in an opposing jersey to contest him.
I feel embarrassed for anyone who claims that James is overrated.
