Blackadder will also be wary about a possible mental shift for this match against the Force, despite them being only one position below the Crusaders in fourth overall. This time last year, on the eve of the test series against France, the Crusaders were lucky to escape with a win at home against the Waratahs, with Berrick Barnes missing a relatively easy penalty on the siren which would have won it for his team.
Apart from Luke Whitelock's move to the bench, the starting line-up is the same as that which held out the Highlanders last weekend.
Crusaders team to play the Force in Christchurch on Friday, kick-off 7.35pm:
Israel Dagg, Johnny McNicholl, Tom Taylor, Ryan Crotty, Nemani Nadolo, Colin Slade, Andy Ellis, Kieran Read (c), Richie McCaw, Jordan Taufua, Sam Whitelock, Dominic Bird, Nepo Laulala, Ben Funnell, Tim Perry. Reserves: Corey Flynn, Wyatt Crockett, Owen Franks, Jimmy Tupou, Luke Whitelock, Willi Heinz, Adam Whitelock, Nafi Tuitavake.
