You don't double LeBron.
he's always surrounded by wing players that can stretch the floor from mid or 3. They've done a very good job surrounding him.
The way you beat LeBron is you take away the paint and you force him to shoot jumpers instead.
The problem is, most coaches like to play LeBron by guarding the drive and leaving him open for jumpers.
He shoots 52% on jumpers and people still guard him as if he shoots 42% in jumpers.
But if you look at how the Heat's team is constructed, they basically can clear the paint when they want LeBron to drive, the way you defend that is you let the power forward and center stand at the perimeter and you keep the paint guarded.
That's why when teams did this the only shot Miami could get was a 3 pointer from Bosh.
Their entire offense is based around the idea that LeBron will be double teamed thus he has players on both sides of the ball for mid range or corner threes, or he has Dwayne Wade on an iso or he'll finish at the rim if the double never comes.
It's very smart.
The problem is when the defense decides to stay home on the shooters LeBron has little options aside from forcing a shot. When they stay home on the shooters only the Power Forward or Center gets the shot. Thus why Bosh got so many three point opportunities once teams found that out. They were willing to sacrifice that instead of a LeBron basket at the rim. This is also why they picked up Battier, because when they switch out the power forward with Battier that corner shot instead of being midrange from Haslem, turns into a 3 pointer for Battier. Make sense? Good
If you double LeBron the Heat's offense is built around countering that and making threes off of it.
Best way to guard LeBron is to shut down the paint and surrender the three pointer and staying home on the 1 and 2.
That way LeBron only has 3 options.
He's gonna drive and try to force a shot and hope for a foul
He's gonna drive it and try to pass it to the open corner shot.
He's gonna take a jump shot.
Most teams give LeBron extra space so that he doesn't do 1 or 2 as he'll nearly always do 3 when left wide open.
Problem is he shoots 52% in jump shots and his jumper should be given a little more respect than that. But teams have made the conscious choice that they'd rather sacrifice LeBron making a jump shot over driving and having all the other options of passing.
Now.... tell me ... if Kobe had those three options. What coach in the NBA would be completely fine with their guy just letting Kobe shoot the jump shot?
The answer...is NONE
