Cian Healy aiming for big impact on Scotland return
Healy will try to detonate a "controlled explosion"
Ireland prop Cian Healy will look to detonate a "controlled explosion" against Scotland at Murrayfield.
Coach Joe Schmidt has introduced Leinster duo Luke Fitzgerald and Healy as the two men designed to bring freshness this afternoon.
"Controlled explosion is what I'm looking for," said Healy.
"I could go out and be a steamroller but I need to be focussed on what I need to do, to be in the right position to put the team forward. That's the big thing.
"I could run around the corner and carry a ball all day long.
"But doing that controlled, where I'm supposed to be, down to the smallest thing of the angle I have to carry at, that's the thing I've been drilling on for the week."
