For any of you Dorito munchin' couch potatoes who couldn't run for a beer, let alone run for 90 minutes, try to understand that the game at this level is INCREDIBLY FAST, and fractions of seconds elapse to determine an offside call that involves less than a yard sometimes. YOU try to run and make that call- I dare you. Yes, sometimes the call is obvious (Tevez) or (Dempsey) but the goal against Germany was literally in/out and 'saved' in less than two seconds. Goal technology is obvious, but determining a 'dive' in a fraction of a second is nearly impossible, and only fractionally easier if a ref knows the reputation of the players (Italy). Some refs allow the game to run, and unless they see blood or broken bones, often resort to no-calls. This should happen more often, given that it is highly probable that a player is exagerating. Anyway, the job is profoundly difficult, and the human factor weighs heavily. And more often than not, justice prevails.
