I waa thinking more for England QC...Redpath or Ojomoh, both of whom are better than Lawrence at IC.
Now that Francis has left, he'd probably be 3rd choice at IC - but even then, it's probably better to leave him at 13 and have someone else IC (Butt and Wright are both perfectly at home in either centre berth, Bailey and Harris are also options there), than to not have Lawrence exploiting that bit of extra time and space.
Again, it's like asking "so who do you play at wing, if you have Watson at FB?"
Hopefully not Manu. Im a big fan of Seb Atkinson...but maybe we go for the club combo Ojomoh and Lawrence.
9 Mitchell
10 Ford / Farrell / Smith
12 Ojomoh
13 Lawrence
