One of my pet hates, commentators calling stuff as definitely done when it's not in an attempt to sensationalise.
Jeff Stelling really annoyed me on Soccer Saturday after Swansea beat Wigan a couple of months ago when he said something afterwards like "is this the result that sends Wigan down?" At that point they were one point off safety.
Alan Parry is by far the worst for this though. Very often he screams out 'great' passes or shots as soon as they leave a player's foot, only to see them fly out of play or roll straight into the goalkeeper's hands.
Remember the orgasm he had when Adel Taarabt tried to do one of those spin on the ball trick when we played QPR at Loftus Road? Williamson (I think it was) read it like a book and intercepted the trick before it was fully executed.
