Some that haven't been mentioned yet
Benji vs Cronulla at Toyota Park in 2005. Scored a long range try, set up another long range try for Pat Richards, and set up try of the year for Fitzhenry to start a huge points avalanche in the last 20.
Robbie Farah vs Souths at ANZ 2009. Threw the last pass in 6 tries, as well as having a big hand in another 2, even though we won comfortably, without him we may have lost.
Anthony Watmough vs Tigers 2009 at the SFS, Manly down 18-0 and he practically got them right back into the game, and would've won it for them if it wasn't for a few moronic plays at the death. Made about 3 line breaks, scored 2 tries and made around 250m in attack from about 20 runs.
Andrew Johns semi vs Manly 2006. Knights were down about 16-0 before Joey scored a try and put Gidley away for another 2. Stood the block for a Mullen field goal, before securing the win with a perfectly placed cross field kick for Carney.
