Why have the Mavricks been getting so many calls this series?

I'm not a Heat fan I actually hate Chris Bosh the dude left my favorite team but it gets annoying watching the finals and watching one team get foul calls for the slightest of contact (some I realize are because the Mavs flop and make it look like its a foul) but Wade and Lebron have been attacking the basket and the same contact is not a foul for them they have to really get hit to get anything called especially lebron.
