Read's return will be a big boost, but just as important will be the mental approach of the Crusaders, who were ferocious at times at the breakdown against the Highlanders.
"That is the challenge," Blackadder said. "If we take them [Force] lightly or if the boys have their heads on the test match the following week [against England] then we will be back down where we were."
One of the reasons why Blackadder selected his "second-string" front row of Tim Perry, Ben Funnell and Nepo Laulala for the Dunedin match ahead of All Blacks Wyatt Crockett, Corey Flynn and Owen Franks was because of last week's All Black training camp in Christchurch.
All three of the youngsters exceeded Blackadder's expectations, with Perry and Laulala scoring tries.
Another who put in an eye-catching performance was fullback Israel Dagg.
Rested against the Sharks, he was full of energy on attack and, while he missed a tackle on Patrick Osborne in the first half, he made up for it with his heroics against the same player as the hooter sounded.
"He was outstanding," Blackadder said.
"We got the balance right in our game plan. We kicked too much against the Sharks when there were opportunities, but against the Highlanders we made good intelligent decisions and Israel was a big part of that."
