Lin should list himself as 6'5" Because Rondo looks like a midget next to him. On a recent tour of the Phillipines, he was standing next to some known height local players, and he was not that tall at all...
Lebron James is good because of his receding hairline, which makes for good aerodynamics. What hair he has on the side act as a spoiler increasing downforce.
He's too tall. If he was shorter, he'd be a tad quicker and be able to get around guys. See: Paul, Chris.
