"The fact that no one has convincingly put us away suggests they are a tough young bunch," says Suasua.
One of that tough young bunch, though he is 26, is fullback/wing Toni Pulu, who ran in two tries with his pace last weekend. He is back playing with a finger that is still broken and needs strapping and a small splint, not to mention an operation as soon as the season is done and before his pre-season recommences with the Chiefs. He looks likely to run out at fullback on Sunday.
"It's our first semi since 2013, so we're excited. All the pressure is on them," says Pulu, who is eligible for no less than five nations - New Zealand, Samoa, Tonga, USA and Australia.
He has no preference for either fullback or wing, and in fairness, it doesn't matter a lot with the Steelers' open style.
Canterbury have recalled lock Dominic Bird and No 10 Richie Mo'unga to their line-up, which has seven changes in all from the starting XV from last weekend against the same opponents.
They will also be on full alert to shut down the Steelers and prevent the visitors' first appearance in the top provincial final since 1997.
