Australian international scrum half Chris Whitaker practices his passing. The 31-year-old, who has recently settled in Dublin with his wife Alison and daughters Lily Rose (4) and Jasmine (3), has already taken youngster Cillian Willis under his wing.
Whitaker said: "We call it the triangle - Guy (Easterby), Cillian and myself are training partners. I'd hope to be of some help with the young guys. It's something we did quite a lot at New South Wales, that kind of mentoring role. You grab someone and bring them along."
