At the end of the day, I can understand players sucking due to physical/talent limitations. But the ridiculously stupid mistakes just kill me.
Late whistles are the surest sign of a ref making a call based on the player. Not that that wasn't a foul, but seriously refs..call it when it happens.
my pet peeve as a fan are those idiotic mistakes and players who aren't good enough to create their own shots, creating their own shots. Or not even trying on defense.
