I think I lost all faith in NFL officiating after the steelers played the seahawks in the superbowl.
The world series was pathetic. These are men who follow baseball their entire lives and get an oppertunity to officiate the most holy of holy series and they made a mockery of some of the calls.
Hockey is evidently bias. Only sport where refs can make judgement calls. Letting the players play and let calls go or by being strict. In hockey you can get offsetting penaltys of a player trips another player and the player that gets tripped dives. How do they both get a penalty. Either it was a trip, or it was a dive. It can not be both.
I dont think its fake like wrestling, but I believe there is behind the scenes reasoning why some calls are made the way they are.
EDIT
I remember watching this once and thinking , "you have to be kidding."
