the rule should be enforced , it shouldn't matter if its a inch or a foot, its still offside. If anything put a timer cap on how long the coach has to challenge. I don't think a team in game 7 overtime having a goal scored against would care if it was just a lil offside. they would still be angry and rightfully so. we have had enough controversy in the p/o, it should be enforced to a tee. players have been cheating with dragging toes and so fourth. if you make a exception to a rule it kind of defucts the purpose
