But didn't it take a combination of injuries and our worst 6n ever before he looked at changes? That's the thing, last time round it seems the changes were forced and not part of any greater planning. If we don't have an absolutely awful tournament, what's to say he will change anything? In 2017 we were still on the winning streak, although playing worse. I'd say the form of the current crop of players we are concerned about is worse than those we complained about in 2017.
Also that was only a year into his tenure so he was taking a good look at various players as he started to put together 'his' team. That's very different to the position we are now in.
On the last generation undroppables:
I'm pretty sure Hartley would have led us in 19, but for injuries. Although Hartley was past his best l'd have supported that for his leadership where there's been a gaping hole ever since. Jones hand was forced, but we need plans to cover injuries - see Cole below.
Brown was only ditched a year before the RWC and Jones didn't give himself time to get a proper replacement sorted - Daly made some howlers in the final and was shunted off to the wing in the next match in favour of Furbank. That Furbank didn't work out doesn't mean Daly's a good FB. Brown wasn't in dire form like some of those we're complaining about now, it was more a case of Jones preferring others with seemingly more rounded skill sets. I said at the time I'd have had Brown in Japan and not taking him was definitely a mistake.
And while Sincks took Cole's starting place on merit, it's a squad game and Cole showed in the final, what many had been saying for ages, that even his one trick, his scrummaging, was shot at that level. You don't legislate for your reserve TH having to play the whole game, but even so he was found badly wanting. I'm not sure there were many other great options - Schonert maybe - but Jones should still have been looking after deciding Hill, who he ridiculously fast tracked, wasn't up to it.
I'm all for experience provided form justifies it. Age isn't a factor per se on an individual level, but allowing a team to age together with several players on a downward path isn't great.
