You are so biased that you arent seeing fouls in an objective way. Haws gets plenty of calls. He's a flopper. Refs know he's a flopper, and most opposing fan bases can't stand that he gets to the line as much as he does.
I'm not bagging on haws -- I say do whatever you have to do to win but people that complain about him not getting to the line enough are like 5th graders watching basketball. Haws runs into guys intentionally - and he intentionally gets tangled up with opposing players to make it look like he's getting mugged. As Rick Barnes says "he's a good little actor."
