For what it’s worth, and I know it’s worth very little at this stage, I would go for this team in the 3rd and final Lions test against Australia.

Starting Bench
Front Row
Corbisiero Corb is an easy choice.  Solid scrum foundation needed. Vunipola Vunipola wasn’t as bad as some people think and will make a better impact sub than Grant
Youngs Youngs not as good as Hibbard in scrum, better in loose and they seem pretty even throwing in to lineout. But with Corbs starting instead of Vunipola the scrum should be slightly dominant Hibbard Hibbard comes on with Vunipola to give more bulk in 2nd half.
Jones Easy pick Cole Easy pick
2nd Row
AW Jones Easy pick Parling Parling as line out leader later on in game.
Richie Gray Gray good around park and good jumper.
Back Row
Croft Line out option.  Very mobile back row O’Brien Covers all 3 positions.  Unlucky not to start but great impact sub
Tipuric Best 7 available
Faletau Has been best 8 on the tour by a long way.  Big ball carrier.
Half backs
Ben Youngs Quick distribution, good box kick (mostly) Murray Good SH.  Unlucky not to start.  For me, Phillips blew it in the first test with his dreadful attempt to stop Genia
Sexton Hasn’t shone so far but still just about the better option Farrell Covers Fly Half and centre
Three Quarters
Tuilagi A much more scary option than Roberts for Australia to have to cope with.
O’Driscoll (captain) Inspiration and captain.  With Tuilangi inside him he should be able to feed off the offloads and create space for the back 3
North Easy pick Hogg Covers all 3 positions (plus emergency Fly Half).
Bowe Cuthbert unlucky, but Bowe is class.
Halfpenny Easy pick
