You realize that during summer league there are guys who pick up 10 fouls, rookies who shoot 15 plus free throws, and those things happen in shorter games, right? The refs are trigger happy C level refs trying to get noticed. Fouls are definitely not called the same way during the regular season as in summer league.

Durant may be a chosen one and get a ton of fouls, but he could also be completely ignored by the zebras. His game is more jumpshooting than driving to the hole though, so I'm guessing he doesn't get the Wade treatment to start off with.
