Brian O'Driscoll pleads for a Lion-hearted effort in series decider against Wallabies CAPTAIN-elect Brian O'Driscoll has called for "the 80 minutes of our lives" to beat Australia on Saturday, or the losing Lions legacy could become a 24-year torture. O'Driscoll said the British and Irish Lions could dig themselves out of the mental hole forced by last weekend's crash in Melbourne for an epic last stand in Sydney. "There was a really good analogy from (flyhalf) Jonny Sexton," O'Driscoll said in Noosa, where the Lions will name a revamped third Test side today. He said it's rare after a Cup final that you get the chance to re-live a Cup final again and put right the things you did wrong. A series triumph might not be as close again until the 2021 tour of South Africa, with the Lions due to tour New Zealand four years from now. O'Driscoll would then be 42, retired and remembered as the prince of centres who went on four failed Lions tours. "We knew we were never going to get it easy against Australia and it has been proved," said O'Driscoll, who is acutely aware the Lions last won a series in 1997. One more 80 minutes this season is all that is asked of everyone in the squad, the 80 minutes of their lives. Installing powerhouse Jamie Roberts at inside centre to crash the Lions over the gain-line, replacing injured skipper Sam Warburton with Irish flanker Sean O'Brien, returning Mike Phillips to halfback and scrum stiffening are four of the likely changes. O'Driscoll lamented silly turnovers, loose kicking and vagaries of refereeing in the 16-15 loss in Melbourne but saluted the Wallabies for their big-pressure play to win. The extra travel to holiday mecca Noosa, rather than a full, settled week in Sydney, was rejected by O'Driscoll as a factor for the Test. "You have to be able to switch off for 24-48 hours away from rugby, even on Lions tours," he said. There is a lot in the bank already so you make sure you don't do too much training this week. It's just about getting detail right and saving the energy for the pitch. O'Driscoll said he did not expect non-Test players in the squad to "go off-tour" and sabotage the quest by savouring Noosa's nightlife. On the morning of the 2001 series-decider in Sydney, whining Lions back-up Austin Healey slated Australia and "the plod" Justin Harrison, a matchwinner that same night. "I have been unbelievably impressed with the whole squad, the manner in which they have carried themselves," O'Driscoll said of the 2013 team. We are still pretty tight and we all want the common goal, irrespective of who is in that 23. If one rousing, farewell chorus of "Waltzing O'Driscoll" is to be sung by Lions fans at ANZ Stadium, it will take a mighty 134th Test from the Irishman. People talk about the momentum going with the team that wins the second Test. I would have agreed in 2001 because it was a comfortable (35-14) victory (by Australia)," O'Driscoll said. Just the way these two games have gone, two points and one point, shows you how tight it is between us. I think the team that turns up on Saturday and gets some momentum from early in the game will get the upper hand.
