Brown in the 33-man squad for Scotland and released again when filtering down to 25-man. Ditto Dan Cole of Leicester. I have no idea why previous posts suggesting Jones is mismanaging them have been flagged as dumb.
Brown, who Jones had previously defended to the hilt from a baying press, is clearly currently 5th pick in the back three, 6th when Anthony Watson returns to fitness. Eddie's been clear on the new pecking order in recent press conferences lauding Daly as a 15 and by the fact either Nowell or Ashton make the bench ahead of Brown, which means he is being kept about in training squads as an experienced backup to the new crop of starters.
He's not in serious contention for a World Cup place if Watson returns to fitness for it, at this rate. We don't know what Jones is saying to him privately about his WC appearance chances, but you can only hope he's not making false promises.
I'm not sure when Brown is currently signed onto for Quins - ditto Cole for Leicester- but if these players in the twilight of their careers sign on to remain in England next season on the basis of a World Cup spot that will never realistically materialise, turning down larger Japanese or French club paychecks in the process, then Eddie Jones will have messed them about by keeping them in the periphery, rather than allowing them to announce their international retirement and determine their own futures on their own terms.
