There's always talk about how well, or not, players handle pressure. But the real pressure this June, is on the respective coaching teams of the leading international sides.
And it's already apparent that some coaches are handling things better than others. Most under pressure is Wales coach Warren Gatland.
He arrived in New Zealand as the Lions-coach-in-waiting and in the space of just 10 days, he's done an enormous amount to damage his prospects.
Wales were good for 60 minutes at Eden Park, which is a source of concern, not pride. Wales competed well in all the right areas, but the point to take is that they lacked the depth of conditioning and personnel to hang in there for the full 80.
This is a test side with aspirations to beat the best in the world and they ran out of puff with 20 minutes to go and lost by 20 points to an All Blacks side that would probably only award themselves six out of 10.
