The Lions have roared and by doing so they have given clarity to coach Warren Gatland in a number of areas.
The first is that by beating the Crusaders with a powerful performance that was driven by the wonderful Conor Murray, he has had confirmation that his tactical approach is on the right track.
Murray was sensational. He took control of the game with his boot - taking his time behind a pack that was holding its own, to then launch a tirade of bombs that the Crusaders couldn't deal with.
He slowed the game down, put the ball in the right places and by going to the air, he made it impossible for the Crusaders to launch anything.
And in doing that, Murray confirmed he's the right choice at halfback for the test series.
