What do you think of my argument about Lebron being the 2nd best player in the NBA?

People say lebron failed in the biggest stage so that makes people like durant, rose, howard, etc. better than him. I agree he has failed in the biggest stage, but do you think those guys would have dominated 3 straight series like Lebron did against the sixers,celtics, and bulls? This is why people are wrong when people say Lebron is not as imporant to the Heat as Wade. When lebron dominated they won. Then when wade dominated and Lebron played bad they lost. Also, the Heat were a pretty bad team for awhile, then here comes lebron and they make game 6 of the NBA Finals. So its clear if they win a ring all the credit doesnt go to wade and just as much to Lebron. Lebron dominated in the playoffs this year more than Rose and them ever have, which is proving him to have better chances of being a champ than them. Also, if you put Rose/Durant on Dwayne Wade's team, do you think those guys would carry Wade like Lebron did in 3 straight series? Probably vise versa right? Which is why Lebron is the better player than those guys.
