He might have signed as Wales coach until the 2015 World Cup but tonight's match against South Africa looms as a watershed for 'Welsh Warren' Gatland.
This World Cup, even though he has an invite to the next one already, seems likely to be the one that marks Gatland's coaching card with a pass or fail mark. Gatland shot to glory with a grand slam and a win in the 2008 Six Nations but has finished fourth each year since.
His opposition in the opening match is also key. Gatland's Wales have come frustratingly close to the Springboks in their three Cardiff losses (29-25 November 2010; 34-31 June 2010; 20-15, June 2008) and a win tonight would seal a great deal - Wales' place in the knockout phase and Gatland's coaching reputation and future. If Wales cannot beat South Africa, they face two pressure matches in Hamilton against Samoa on September 18 and Fiji on October 2 to decide their World Cup fate.
Wales have beaten the Springboks once in 25 attempts; a 29-19 victory under the stewardship of one G. Henry in June 1999. However, a loss and any further setbacks may set the volatile Welsh rugby mandarins casting critical glances in Gatland's direction, even though he signed on to 2015 late last year.
Win, and Gatland could have the rugby world open up before him. If you believe in the theory that a contract is a piece of paper which can be torn up with the right arrangements made, it is not beyond the realms of possibility that Gatland could look at the All Black coaching job for the next World Cup if the new incumbents - whoever they are - don't do the business in the next couple of years.
