My 2c re: Jones at Reds. I thought it was too soon for him to be involved in Australian rugby after his sacking from the Reds. His head didn't seem in the right mindset at the time, which, coupled with a team that had lacked direction for a number of years was a recipe for disaster.
I think he will do well with the England squad - he won't need to place as much attention on the scrum as he should have done with the Wallabies during his tenure as the Premier League coaches will do that for him and the mindset regarding scrums in England is different than what it traditionally has been with Australia. He will improve the skillset of the players, particularly the forwards catch and pass. England will be a much more dangerous proposition at RWC2019. If they improve quickly enough the Lions tour to NZ in 2017 (particularly if EJ (Eddie Jones) is on the staff as a technical advisor) will be very interesting.
