Jack Conan is expecting a tougher challenge from Italy for the Ireland defense in their upcoming Six Nations match. After a dominant win against France, Ireland is currently on track for a second consecutive Grand Slam. However, Conan believes that Italy will pose a different threat with their attacking style of play. He acknowledged Italy's quality and their ability to score impressive tries, as shown in their game against England. Conan also praised the performance of young lock Joe McCarthy, describing him as a destructive force on the field. Off the field, McCarthy is described as a placid and chilled guy who can switch on his intensity during games. Conan believes that McCarthy has immense potential and is excited to see his continued development.
