Easterby has made just two changes for the Scotland game, bringing in Peter O’Mahony and Robbie Henshaw while retaining Sam Prendergast at fly-half ahead of Jack Crowley.
The battle between the out-halves has attracted intense debate, but Easterby believes the attention is “part of their growth”.
“Jack had a bit more of that last year throughout the Six Nations and dealt with it really well.
“He’s also had a period of not being selected every week so that’s a different dynamic to what Sam’s going through at the moment.
“But they would share experiences with each other. Jack’s been through that and we’re fortunate to have Johnny [Sexton] in camp as well to impart some of his experiences in that position over the years, his battles with ROG [Ronan O’Gara] and how that developed over time.”
Easterby added: “They’re pretty comfortable in their own skin. They are down to earth, level-headed, extremely competitive and ambitious but understanding as well that there are ebbs and flows in life, in games and your selection.
“They’re just figuring out a the moment how to get through that and we’re supporting them the best we can.”
