This is an argument I would like to end with "Yes, he is," but I will elaborate.
James was deemed as the "chosen one" before he ever stepped onto an NBA court. While that was a high expectation, LeBron has continued to improve over the years to become the most talented player in the game.
Offensively, James uses his big body and quickness to brutalize any type of defender you put in front of him. His jumper is noticeably improving, making him more than a one-dimensional player he was once considered.
However, James is still most dangerous when he gets to the rim. He has the leaping ability and poise to either throw down a serious facial or finish with finesse over a defender.
While not the best free-throw shooter in the NBA, LeBron does show he can get the line at a high level. In his career, James has averaged 8.9 attempts a game while converting on just under 75 percent of them. For you mathematicians out there, that is 24 percent of his career scoring average thus far.
Defensively is where LeBron has most significantly improved, landing three straight All-Defensive First Team selections.
Once again, this is an area in which LeBron's athleticism is really handy as he has the ability to defend any forward or guard in the NBA. James has averaged 1.7 steals per game with his knack to apply pressure and pick off errant passes.
James rounds his game out by being a solid rebounder and a top passer in the NBA, averaging seven a game for both statistics.
LeBron will threaten for a triple-double any night. The scary thing is he is only getting better.
