Wade is taking a team that, without him, is headed for a similar fate as Washington, and single-handedly putting them in the playoffs. They're going to be the 5th seed, at the very least, I expect them to move into 4th when its all said and done. Wade is the team's best defender, EASILY, and also one of the very best in the NBA. He's the team's only offensive facilitator, and he again is one of the best in the league at that. Lastly he's one of the top 3 closers in the game, and hits countless amounts of big shots for Miami, oftentimes just to keep them in games.
Take a look at the garbage Wade is pulling behind him into the playoffs. Not a single big man on that team can defend. They have no depth at those positions, their best player down low is Haslem. JO'N is a dog who can't play interior defense anymore and the vast majority of his offense comes from jumpers. Blount and Joel Anthony are terrible. Beasley's a good second scoring option, but defensively he's a disgrace. Moon is terrible. Quinn is terrible. Mario Chalmers can shoot and play a little defense, but other than that he does nothing. James Jones and Luther Head have been good bench players, but they have given Miami nothing whatsoever. The only depth player they have is DQ.
Minus Wade (for a season, obviously for single games they could give teams a hard time, like tonight against the C's), this team is a failed abortion.
