Pauliasi Manu has come in and added bite to their scrum judging by the way the Blues crushed the Chiefs at the set-piece in their last pre-season hit out. Jimmy Tupou, the versatile Crusaders forward, could come of age with game time and Michael Collins, who has arrived from Wales via Otago, may turn out to be a smart piece of business if he continues to provide direction and accuracy at fullback.
And of course, the Blues also landed Sonny Bill Williams and halfback Augustine Pulu to give them a little glamour and confidence that they are a franchise for whom the best players want to play. The new boys join an established core that includes Charlie Faumuina, Patrick Tuipulotu, Jerome Kaino, Steven Luatua, George Moala, Rene Ranger and Rieko Ioane and the Blues, on the basis of their personnel, suddenly have a formidable feel.
They have been here before, though - between 2004 and 2012 they were a squad full of match winners but no idea how to bring all the component pieces together. But Tana Umaga made good progress with a young and inexperienced squad last year and has strengthened his coaching team by bringing in Steve Jackson as an assistant.
Having had a year to get under the bonnet, it feels like they have fixed the clunkiest parts of the engine. How much so will become evident tomorrow night. It's a game the Blues know they have to win, for the simple reason, that good teams just don't lose to the Rebels.
Super Rugby's opening game will be well short of glamour, but won't lack significance.
