Fullback Ben Smith, who has missed the Highlanders' past two matches with concussion, is likely to be available to play the Hurricanes in Wellington on Saturday, and his versatility, plus that of Dagg and Beauden Barrett, is a huge plus.
Either Smith or Dagg could play on the right wing, leaving first-choice first-five Barrett to play at fullback and Aaron Cruden at No10.
Both Smith and Dagg possess pace and good kicking games, but there is nothing like having a specialist finisher like Naholo or Milner-Skudder at the end of the chain.
Milner-Skudder, who scored a try in the 2015 World Cup final, was one of the stars of the tournament, and few players possess his agility and pace off the mark.
Likewise, few possess the speed of Naholo, who was taken to the World Cup despite only just recovering from his broken leg but couldn't quite reproduce his Super Rugby form.
"What are the rewards of taking Waisake?" Hansen asked before the World Cup. "Well, he is a try-scoring machine, he has X-factor and he brings something to the team that others in the group don't bring."
In his first test after the World Cup last year, against Wales at Eden Park, Naholo had a difficult first half defensively before showing his class with a recovery, including a second try, which owed much to his mental strength and Hansen's faith in him. Rather than replace the 25-year-old Naholo, Hansen opted to substitute left wing Julian Savea.
"We talked out on the field, and he said - well, I won't say what he said, you can't write it - about his first half," Hansen said after the All Blacks' 39-21 victory. "I made the comment, 'son, the pleasing thing is you came through the other side of that'. That takes a lot of effort - mental effort, particularly. We know he's really talented. He hurt them even in the first half, he scored a lovely try."
