What's really scary about this is that there's a legitimate chance LeBron James is going to keep getting better over the next couple of years. These past five have been quite a treat for any basketball fan, as LeBron has dominated every single aspect of NBA basketball. He's won an Olympic gold medal in 2012, two NBA titles, and made a "decision" that is still one of the most talked about moments in league history. His play on the court has been without parallel; of players to average at least 20 points and seven rebounds per game over the last five years, nobody is even close to matching LeBron's assist totals (Blake Griffin is the closest with 3.6 per game). The only question with LeBron is just how much greater he can get?
