Justice for Jac. A place on the bench and virtually assured of playing a part in a meaningful part of the series. He will become a test Lion, and rightly so. It would be churlish to deny that Tom Curry was outstanding in the fist test . His physicality along with Beirne, Genge and McCarthy established the dominance that should take the Lions to a 3-0 series whitewash. However, Morgan deserved to be coming off the bench last week and will get his just deserts on Saturday. So that’s one selection I agree with, but I’m struggling to understand a couple of the others. From all accounts, the weather in Melbourne is going to be awful this weekend. Furthermore, the Wallabies have to throw the dice to keep the contest alive by starting Valetini and Skelton. Australia were blasted out of the game in the first half in Brisbane and start this decisive match fully loaded. That is why I am a little confused with Genge dropping to the bench. Skelton and Valetini will give it everything for 50 minutes and try and build a lead. It can be hard to chase a game in the wind and rain, and with 90,000 fans at their backs the home side may be able to hang on for a win. Im a big believer in scoreboard pressure. Why not meet their firepower head on, rather than look for impact from the bench? The Lions should have been 40 points up at half time in the first test had they not binned three regulation try opportunities. When you dominate like that, the bench is irrelevant. In contrast, in midfield Farrell has gone with power and Bundi Aki comes in. You don’t pick him for his side-step. The Lions look to be more direct behind which makes sense since outmuscling Australia is the safest way to secure the series. Finally, picking his son on the bench is a little nepotistic. He has pedigree no doubt but he hasn’t played a high quality match for months and now he’s on the bench for the Lions. With that rationale, if a scrum half goes down before the third test Gareth Edwards will be dusting off his boots. What has been a little strange on this tour is the different approach the test team has taken compared to all the other matches. In the provincial games the Lions have been happy to go wide early from set-piece, they have largely ignored crossing the gain-line and they have under-resourced the breakdown. As a result, they have been capricious. Great when it comes off, shapeless when it doesn’t and gets turned over regularly in contact. There was none of that nonsense in the first test and I suspect the second test will be the same. I wonder if in the back of Farrell’s mind he is beginning to consider life after the Lions, and returning to his Irish job in eight days' time. James Ryan on the bench gives the Lions four locks in the 23. That seems excessive. Aki and Porter promoted after their counterparts played key roles in the first test also feels harsh on the incumbents. I’m sure Farrell is picking on merit, but these changes will not harm his standing with his Irish players either. This weekend the Lions have the opportunity to seal the series. They were at 75% last week and still won comfortably. It comes to something when Lions fans are hoping that the opposition can put up a decent fight to breath some life into the tour. I somehow managed to predict the precise winning margin in the first test and so with confidence at an all-time high, I will boldly foretell of a 12-point winning margin and series clinching victory for the Lions. Even on the eve of a potential Lions series win, there is another head coach getting the headlines in Wales. Steve Tandy has been unveiled as the Wales head coach. The worldwide search for a successor to Warren Gatland ended in Tonmawr. There are many things I like about Steve Tandy’s appointment. He is Welsh, which is important. It means he understands the culture, the tribalism and importance of rugby in Wales. He has earned his straps outside Wales and can bring that experience to Wales. He will live in Wales and as a result he will be visible and have a presence across all tiers of the game. He will be completely dedicated to his weighty role and won’t be popping up at every after dinner event across the land or writing columns for the London papers. He will be unflinchingly honest in his assessment of performances and where things need to improve. And he won’t indulge in the petty pre-match mind games designed to distract or deflect from the hard reality. Over time I am sure his personality will emerge and the team will take on some of his obvious characteristics. Tenacity, integrity and intensity. The announcement that the WRU will play a part in selecting his backroom staff is interesting. There are pros and cons to that but what this signals more than anything is the growing influence that director of rugby Dave Reddin is accumulating within the organisation.
