Next year he'll be without Carter again who has confirmed he'll be resting his battered body for another six months.
Throw in the fact that the bulk of his All Blacks meandered through the first half of the season - partly because they are denied a proper pre-season; partly because they consciously pace themselves knowing what lies ahead and partly because these days anyone with 20 caps or so doesn't play their way in or out of the All Blacks on the basis of their Super Rugby form.
Blackadder would be within his rights to wonder whether the time has come for test football to take some pain: if players need extended breaks - and there is no dispute that many do - why don't more get pushed down the Conrad Smith route of skipping end of season tours instead of Super Rugby.
It's always Super Rugby that has to be sacrificed - not only with top players being sanctioned to skip it, but with the ridiculous three-week break for the June tests.
If the competition wants to build its revenue and standing post-2015 then it has to give the impression it's viewed as a bit more important than it currently is. It's all well and good saying Carter's absence next year will provide an opportunity for a new player - maybe Tyler Bleyendaal or Colin Slade.
But while that's lovely for them, it would be better for everyone else if a fully fit Carter was in the No 10 jersey. It would be better for Bleyendaal if he was wearing the No 10 jersey because he had earned it ahead of Carter.
The ITM Cup is all about development - Super Rugby should be all about the best playing the best.
The Crusaders will start next year with one leg metaphorically in a cast - they won't make excuses but everyone can see they will have one.
