So now it's time for the backs. My general view is that most of the selections are either about depth or age. Jones is either looking to strengthen depth or depth is good enough that he is looking to the future. I think he has a good idea of his squad for 2019. I have included players ages as well, hence the number.
Just some quick assumptions, but regulars are those who have been playing recently or trained often enough, example Ellis Genge for me is now a regular in the squad and above the likes of Matt Mullan. When it comes to missing out, I am looking at players who have recently been called up and then dropped. There may be others, but this is more a look at who has been picked than not.
So here are the backs.
Scrum Half:
Regulars: Danny Care-30, Ben Youngs(Lions/now absent?)-27
Called up: Jack Maunder-20
Training Squad: Willi Heinz-30
Missed Out: Richard Wigglesworth-33, Dan Robson-25, Joe Simpson-28
Summary: Here Jones has his 2 main guys. Wigglesworth is now too old, depite how well he is playing. Maunder is being given a chance. Heinz, some experience whilst training? Not sure what Robson and Simpson are doing wrong really. You could say not playing regularly enough, but then that would also apply to Maunder. It's possible Jones wants sniping scrum halves, instead of kicking ones.
Fly half:
Regulars: Owen Farrell(Lions)-25, George Ford-23
Called up: Alex Lozowski-23, Piers Francis-26
Training Squad: N/A
Missed Out: Freddie Burns-26, Danny Cipriani-29
Summary: Now this is the start of a very versatile backs division, where many players cover more than one position. Farrell and Ford are clearly there. Lozowski is young, but playing well. Francis is new and unknown, but supposedly very good. Burns has played well recently, but probably left it too late to feature and needs some consistency into next year. Cipriani hasn't played regularly and can be too inconsistent. He is also getting older how, which I think counts against him under Jones.
Inside Centre:
Regulars: Owen Farrell(Lions)-25, Henry Slade-23
Called up: Harry Mallinder-20(Also possibly full back)
Training Squad: Ryan Mills-24
Missed Out: Ollie Devoto-23
Summary: Farrell has taken this spot, with Daly also providing cover. Slade hasn't done much wrong, but the Ford-Farrell combo as worked really well. Mallinder is young and coming up, but apparently Jones also sees him as a full back, so not sure if he would play here. Mills training as an outside option. Devoto has had a look in with training squads, but I guess no longer fits into Jones' plans. I think he wants a 12 who can kick and pass to a very high standard.
Outside Centre:
Regulars: Jonathan Joseph(Lions)-25, Ben Te'o(Lions)-30
Called up: Sam James-22, Joe Marchant-21
Training Squad: N/A
Missed Out: Luther Burrell-29, Kyle Eastmond-27
Summary: Joseph and Te'o on Lions duty. If Tuilagi was fit and playing would he feature??? For me he is in the same mold as Te'o. Burrell is obviously out of favour. Eastmond has completely fallen away. That leaves Sam James and Joe Marchant, who are young and competing for depth.
Wings:
Regulars: Elliot Daly(Lions)-24, Jack Nowell(Lions)-23, Anthony Watson(Lions)-23, Jonny May-26
Called up: Denny Solomona-23, Joe Cokanasiga-19, Nathan Earle-22
Training Squad: Marland Yarde-24
Missed out:, Christian Wade-26, Semesa Rokoduguni-29, Matt Banahan-30, Chris Ashton-30
Summary: A lot of depth here and versatility. Watson and Daly can cover full back as well and personally I think Watson will be there very soon. May has pace to beat almost anyone. Nowell is very good all-round. Solomona is new, but has played incredibly. Cokanasiga and Earle are young to provide future options. Wade is vulnerable defensively, similar to Ashton. Both great at finishing tries, but I think Jones wants wings who are strong defensively too. Rokoduguni seems to be out of favour and while Banahan has played well, he isn't what Jones is looking for. Yarde in the training squad, but you have to think he's had his chance too.
Full Back:
Regulars: Mike Brown-31
Called up: N/A
Training Squad: Mike Haley-22, Jason Woodward-26
Missed out: Alex Goode-29, Chris Pennell-30
Summary: Last the weird one. All faith in Brown, who personally has slowed down and is not as big a threat anymore. I think Watson will replace soon. Supposedly Mallinder is also seen by Jones as a full back. Haley and Woodward training as options. Pennell was talked about, but has disappeared and is now 30+. Goode…I guess to inconsistent for Jones. He's had his chances, but hasn't broken past Brown. Personally Goode plays far better for Saracens than he does for England.
So overall I think Jones has an idea of what he wants, and has picked many players who can cover other options and are solid players all round, instead of strong in one area. For me the real areas of concern are 9 and 15, where there is a lack of depth and no obvious player/players who can step up instantly.
