I don't see the point in picking Croft largely because he's outstanding in the line out and then throwing to the front or middle every time. Plus, if we do throw to the front, and we don't maul, we need a 12 who's gonna get us over the gain line more consistently than Davies. I would still pick Croft, but we should be much more adventurous on our throw.
I would bring in Felateu at 8 for his work rate and graft, and because i think we lacked an extra tight carrier in the first test. Heaslip does a few eye catching things, but last week there was too much emphasis on the front 5 doing the carrying around the fringes. Prey Corbs is fit (big, big loss if he isn't) and Parling in for POC. Grant, Gray and Tipuric/lydiate come on to the bench.
If Roberts is fit he come straight in for me, essential for our game plan and Bowe on the bench. Would love to get Tuilagi involved some how, because i think he could really hurt the Oz midfield, but i don't see how we can. See how he goes tomorrow and maybe he'll be foisted in somewhere for the 3rd Test.
Meanwhile, Ozzies in a bit of a shambles. From a Lions pov Ashely-Cooper being out would be massive. Easily their best defender in the back line.
