Nah I don't agree with that. Those sides are at least as good as the 4th place Welsh side he got two against in 2010, or their RWC warm up team from 2015 and the 4th place Scottish side in 2016. He's played under Kidney and Schmidt when players like Bowe and Trimble could score tries at times, he has one try against Rugby Championship opposition in 15 games and the same strinke rate in 15 games against England and France. For a player with his ability, who is often branded a "world class finisher", and the hype that surrounds him when he performs for Munster it is undeniable that he has had an underwhelming international career with a strike rate and tier 1 strike rate only marginally better than Fergus McFadden's who no one has ever claimed as world class, outside maybe his defensive work, and was often scrutinised for his lack of finishing ability. (On average a try in 38% of his games with 1/3rd against tier 1 opposition v McFadden's try in 32% with 3/10 against tier 1)
Now is the time to change that, he's in the form of his life and should be one of our two main try scoring threats in a strong and settled side for the remainder of this RWC cycle, he has a class of player behind him that will require it too.
