In his book "Relentless," legendary NBA trainer Tim Grover talks about what motivates his superstar clients Michael Jordan, Kobe Bryant and Dwyane Wade. Then he talks about different character types, the highest of which, in his judgment, is what he calls a "cleaner." Jordan, Bryant and Wade are, Grover says, all cleaners.
What about LeBron James, whom Grover does not train? Grover met James when the then high-schooler hanging around Grover's Chicago gym during Michael Jordan's comeback pickup games.
James is not a cleaner, says Grover -- who also primarily credits Wade with the Heat's 2012 title. James has a chance to become a cleaner, however, says Grover, right now in these playoffs.
