I agree re the low likelihood of the older forwards reaching the next RWC but they are definitely not "spent forces" - that headline is largely click-bait because the article is more tentative. But, as usual after a major loss, it is easy to pick on purported problems.
At this end of the season, the game tonight will mean much more to the All Blacks playing - there's so many players with a lot to prove - than it will for most of us. Our "second" team should win this one but honestly a loss now has a lot less impact than the loss last week. That has cast such a large shadow that it's hardly likely to increase the disappointment we already have.
