Recent articles suggest that Eddie is considering Atkinson as a 10 for the summer.
With that in mind, Charlie may be a little reductant to effectively switch positions.
That being said, Eddie loves a bit of versatility
I wouldn’t believe that rumour, tight head or 2nd row maybe, but not his main position.
I think Charlie will be looking at the England situation from beyond RWC 23.....Jones' way of winning games with England c.f. RWC vs NZ is unlikely to change and the preferred players are pretty much all in place already. England do have real problems in terms of who to play beyond their current first 23 and Jones' odd selections like Martin from Tigers seems strange when compared the players like Marcus Smith and others who are Prem vets in comparison
I'd be v surprised if England changes much from here on in - unless they have another poor 6Ns, when there might be some late and wide ranging changes, including the coaching team.....England play in a certain way - when working, v hard to stop, if stopped, lacking the thought processes to change.
Charlie might get game time in the summer - but I v much doubt any of the new/newer players will likely be anywhere near the RWC.
