I'm not sure if you've ever played basketball before, but fouling is a way for lesser players (Kidd, Stevenson, Marion) to bring themselves up to the level of greater players (Wade, LeBron), which is exactly what is being allowed to happen, by the referees not calling blatant fouls on the perimeter and at the basket. Meanwhile, Nowitzki is going to the line on jump shots. Chandler is getting more loose ball foul calls drawn than Shaquille O'Neal in his prime, and Marion is allowed to shuffle his feet every time he throws up a hook shot.
