Going forward I'd leave today's starting 15 unchanged, other than Itoje in for Lawes and Nowell in for Ashton. Maybe Underhill would be better than Wilson; both have their pros and cons but I'd leave Underhill on the bench purely because I wouldn't change the current winning formula. On the bench I'd make a few changes:
Hartley in for LCD - LCD's better in open play but hasn't done enough to make his poor set piece worth the risk.
Genge in for Moon - he's just a superior all-round player, although Moon has always looked solid in an England shirt and is a solid backup.
I'd keep Cole - he did more in today's cameo than Williams has done.
Lawes and Underhill at 19 and 20.
Robson and Ford at 21 and 22.
Cokonasiga in at 23 for his impact.
As a Leicester supporter, Cole is a penalty machine.
