I feel for some of the guys who are good enough, but don't get a chance in the first choice side (Dom Day, and to a lesser extent Tipuric) - I know this is just a nothing game, but it'll still be in the coaches heads when they're looking at them come RWC time.
Actually...
Right now, Gatland gets to find out which of his players have cool heads and guts; they may be outclassed, but either a player has the ability to keep playing bravely and sensibly under pressure, or they're not ready for the World Cup. Tbh, I think Gatland would have reckoned his boys weren't this badly outclassed.
As for Schmidt - again, he gets to see who's making the right decisions to be clinical, and he also now gets to see who gets comfortable. Not bad things.
