This is what I'd like to see (assuming it's a 36 man squad and not a 32)
LH - Smith, Carre, Thomas
Hooker - Owens, Lake, Roberts
TH - Lewis, Francis, Wainwright
Row - AWJ, Beard, Daf Jenkins, R. Davies
Flankers - Tips, Morgan, Basham, Tshiunza
8 - Faletau, Moriarty
9 - Williams, Hardy, Blacker (Webb is injured by the looks of it)
10 - Biggar, Owen Williams, Jarrod Evans
12 - Kieran Williams, Hawkins
13. North, Grady
Wing - Adams, Dyer, LRZ, Lane
15 - Williams, Ioan Lloyd
There's a few there that you definitely think won't make it. Ioan Lloyd is the obvious first one, imagine it'll be Halfpenny but if Lloyd isn't there I'd like Tom Rogers to be selcted even though he seems to play more on the wing. Lane is more likely but Cuthbert or a Giles/Conbeer/Ashton Hewitt would be my preference over him personally personally.
Other than that all of my Center picks, other than North, are far from guaranteed but there's a decent chance at least 1 of those 3 will be selected. You could see Patchell getting selcted and to a lesser extent Priestland as well so those 2 back up 10 positions up for grabs.
In the pack I don't think Basham will be quite up Gatlands street so expect to see Reffell selected which I won't be unhappy about even though I love Basham. Rhys Davies and Daf Jenkins are 50/50 perhaps Seb Davies ahead of them but with Rowlands out we don't have loads. Wainwright gets in by default as I don't know what other TH we'd select who is available and if Dillon Lewis doesn't recover in time we could be in a bit of trouble there.
