Sounds like you just like the sound of your own voice. You seriously need to know who Lebron makes better?
LeBron made Dwayne Wade and Chris Bosh better? How about Kevin Love? Mike Miller played better last year on Memphis than he ever did on Miami or Cleveland. What player came to a LeBron team and produced more than their previous team? It's not meant as a criticism. It's truth.
LeBron is a great player and he makes every team he's on better because he's a great player. Pretty simple. I don't think the Cavs are losing in the East because of him. LeBron is still the best player in the league. The rest of their team sucks and/or lacks experience. Every one of the Heat teams was better than this year's Cavs. The league has gotten better as LeBron's teams have gotten worse. Everyone but you realizes that.
