You can struggle for form and you sometimes need a bit of luck, but the main thing is to come through unscathed.
Then you can kick on.
Individually, the biggest plus was the form of Taulupe Faletau, who was everywhere and made an incredible try-saving tackle.
Faletau was world class and showed that the widespread assumption that his cousin, Billy Vunipola, would be the automatic No 8 for the Tests was wrong. After an injury-affected season, Faletau was fresh and fit.
That is a huge bonus for the Lions, because if you go into the tour and the tests feeling you are already a man down, that one of your gun players is missing, it can affect you.
Any danger of that has been dispelled. Billy Vunipola is a terrific player, but with Faletau in this form, the Lions have a player of equal stature and ability to step into his shoes.
Watching the Barbarians, who have had scarcely more preparation time than the Lions, reminded me why New Zealand are so good.
Those involved were fringe Super Rugby players, mainly stalwarts of the Mitre 10 provincial competition, but they were packed with instinctive players. Their basics were excellent.
What the match did was make me excited about the matches ahead. The strength of those Super Rugby teams and the Maoris that lay in wait is phenomenal, and they are revved up for this tour.
The Lions will have to respond in kind, which they are eminently capable of.
