have i seen a game where a ref made a call that decided a game this year? no, not one call decided a game but failure to make calls on muggings inside and outside of the box does decide games brecause the tenor or the game changes when the ref allows physical play to dictate instead of passing and combinations. the lack of calls is what usually decides games because defenders get more and more aggressive to the point that they put saddles on fowards in the box. so no, i havent seen a game decided by 1 bad call, but i have seen several decided by failure to make the calls so that we watch football instead of the beautiful game.
