Looking at who could make a possible 32 man squad?
LH looks pretty settled tbh Marler and Genge with Bevan Rodd third choice. Obano is injured and no obvious other choices available at this time other than possibly VRR and Elrington who are playing well tbf but doubt Eddie will see them as anything but backup options
HK another pretty set LCD and George have shown they are Englands best two options with Blamire as 3rd choice. Again there are other options but not that are really ready yet imo.
TH Sinkler will be 1st choice and I think Eddie will go with Davison due to being comfortable on both sides of the SCRUM which makes him perfect for a World Cup squad. I do however think that Collier will come in over Stuart. Stuart can be a good player but just hasn't been in good form, Schonert could also be an option but again is probably only thought of as backup. Heyes is probably the next off the rank but is still young and is behind Cole at Leicester. Prop is probably Englands weakest area atm but some good youngsters coming through in both sides but bar Rodd, none will be ready for the WC.
SR Itoje and Hill will most probably be the starting pair with Lawes and Martin as 6s slash SR options. However I would like to think Eddie might experiment with someone like Isiekwe, Wells or Ribbans who have been in really good form and are all better than Ewels and Hill imho. We really lack depth in this area atm with only Itoje, Ewels and Hill prominent starters, especially a big enforcer type like Chessum or Tizard especially with Launchbury not 100% fit.
BR as mentioned Martin and Lawes will be the 6s and Curry can obviously play there and will undoubtedly be there with Underhill as the 7s. Dombrandt is our best option at 8 and also adds cover for Itoje being g able to play at 4. probably need another 8 in there too with a fair few options tbf Chick, Barbeary, Willis and Simmonds. Any of these options would be good but I would like to see Barbeary given a chance even though I think Willis is the more accomplished player atm Barbeary I think will be better given time.
SH given the depth of quality youngsters we have here atm you could be forgiven for not wanting Youngs in the side but he is the most experienced SH that is a part of the England squad. He will be a big help to players like Randall, JVP, Quirke, Mitchell, Maunder etc still a few more. I think 3 SH with Youngs, Randall and Quirke the three I think we'll see with Randall and Quirke getting equal opportunity, still quite young to be starting imo.
FH tbh I think only two Fly Halfs will be there as you have cover elsewhere in the squad tbf and even though Ford is the best no.10 in the league atm Eddie will choose the young gem that is Marcus Smith as he is the future of English rugby and will want to mould him into the squad and golden boy Farrell should he be 100% fit even though imo he is the one holding England back atm. Personally I think we should be focusing on the young talent because we have some quality young 10s around but it's Eddie and he loves Farrell.
CTS Should he be fit Tuilagi is the only real option at 12 atm. Atkinson is decent cover and again you could look to Kelly, Ojomoh, Dingwall and Lawrence as offering younger but promising options but in Tuilagi you have a glass cannon. 13 is a lot easier to decide tbf Slade is the mainstay and I think is better with a bigger option alongside him in Tuilagi rather than Farrell. Marchant the 2nd choice. I don't think there are many other options around at this time to overtake those two
BACKS May imo should be overlooked in favour of younger options but he is another golden boy, Radwan with his pace, Malins versatility and Stewards prowess in the air is a good starting back 3 and I like the idea of OHC being in the squad as he adds pace and also being able to Play 13. Furbank will probably be there too but I think Steward and Malins is enough and would prefer his place to go to another Centre to add better depth where needed.
