The All Blacks have embraced a drawn series with the British & Irish Lions as a much-needed reality check, which has sent them into overdrive these past two weeks refining skills, honing strategies and touching up their conditioning.
The Lions exposed flaws in the All Blacks and the question that will be answered later this week is whether the coaches believe that all the problems can be fixed by hard work or whether they need to consider personnel changes as part of the overall remedy.
Since Steve Hansen took over as head coach in 2012, he hasn't tended to react to poor performances by making selection changes. Not immediately, anyway, and the philosophy has typically been to let players who didn't deliver have the opportunity to put things right next time.
The most recent chance to put things right was the third test against the Lions. The All Blacks lost the second test and the pressure was on for largely the same team to bounce back and perform well in the decider. They didn't - and the coaching staff would have asked themselves some hard questions.
Did, for instance, the pack have enough attitude and presence? Did they do enough to get the All Blacks over the gain-line when they carried the ball and made their tackles?
