Players returning from injury is commonplace but a coach doing the same is a rare occurrence.
But that's exactly the scenario that Welsh rugby fans will be hoping pulls their team out of a miserable, recent slump which has resulted in embarrassing, consecutive losses to both Argentina and Scotland.
Warren Gatland, one of the best New Zealand coaches to ply his trade offshore has returned to resume command over Wales and prepare them for this test against the All Blacks in Cardiff.
After fracturing both his ankles severely in an awful fall at Waihi Beach during a holiday there, the man from the Waikato has only now been able to again fulfil all of the duties that are demanded of an elite coach.
Gatland has undoubtedly reinvigorated Welsh rugby since his tenure began in 2007.
This rebirth in performance and pride was no more evident than when Wales came so close to playing the All Blacks in the 2011 World Cup Final and then rule supreme in the 2012 Six Nations Championship.
And only a few months back, a confident, plucky Wales gave the Wallabies a real fright, running the Aussies desperately close in all three tests in Australia.
All of which explains that despite the weak Welsh displays in their last two tests, the All Blacks won't bring a whiff of over-confidence to the occasion when they run out onto the Millennium Stadium to face the Red Dragons in a few hours time.
That's also why Steve Hansen was always going to select his best XV for this clash and put an end to the brief bout of rotation that he indulged in against both Scotland and Italy.
Behind all the success of the men-in-black under Hansen has been the magical blend of experience and youth, ranging from the champion warrior, Richie McCaw who will play test number 115 to the sensational rookie, Julian Savea with just seven tests to date.
Unfortunately, Wales has many of its' top players unavailable through injury and even though there is still a good amount of experience included, I strongly suspect they will lack sufficient pace, power and accuracy to bring this fanatical rugby country victory against the team it craves to beat the most.
