A comparable between Gatland, Henry and Steve Hansen, all of whom have coached Wales at some point in their careers, is that the rounded up percentages see Henry (59% win rate) first, Hansen (53%) second and Gatland (51%) third; the latter though has an impressive 69 per cent win rate in Six Nations Championship matches.
Tadhg Furlong and Iain Henderson will sit out Ireland's Six Nations clash with Wales.
"They are world class players, you don't suddenly replace world class players, but we're a lot more focused on who we do have".
Porter and Farrell will both starting in the Championship for the first time and Schmidt is focusing on their opportunity to impress, rather than the absence of Henshaw, Furlong and Henderson.
With Lions prop Tadhg Furlong ruled out due to injury, Ireland head coach Joe Schmidt has opted to start Leinster's Andrew Porter at tighthead prop ahead of Munster's John Ryan who is listed among the replacements.
Which is why Ireland will take a measure of fear into the Six Nations match with Wales on Saturday at Lansdowne Road.
"He kind of found his feet a bit against Fiji, I thought he was really good against Argentina and I think he showed there's a bit more to Chris Farrell than a bludgeon - nice soft skills and a tight pass, he's got a good length in his pass". "That's not ideal but if you want to learn, what better environment than what will be a really white-hot atmosphere on Saturday".
Ireland failed to score a try last season in a Test against Wales for only the second time since 1994.
"I think the scrum's going to be 50:50".
"Over the previous year and a half with what he's had to take in his stride, changing sides on the scrum and how he's developed that part of his game, it's more exciting than nervous to see what he's going to provide".
Healy partners captain Rory Best and Porter in the front row for his 76th cap and says the injuries to Furlong and Henderson will cause no disruption to the pack.
"He'll be behind Ports, so that's going to be a strong side".
For the record he won 33 of 57 games with Australia including leading them to the 2003 World Cup final which they lost to England, 34 of 48 at Japan, including the Cherry Blossoms' World Cup win over the Springboks and 24 in 25 matches with England, Jones sole defeat coming against Schmidt's Ireland at the Aviva Stadium a year ago. "I don't think I could have done anything more to make sure I was ready", he said.
