there's merit to the approach Wales took in trusting their key players to bounce back following their Scotland defeat. To a man they stood up against Ireland. If Schmidt selects the same team again, they'd better perform similarly.
That doesn't necessarily follow. As far as you know Wales could have won by 30 if Howley picked a different team. You've no basis for a comparison because Howley hasn't given you the chance to see what the competition can do. And even if it does follow i'm full sure those same players are gonna let Howley down in the very near future if change doesn't occur. Even under Kidney we were capable of one off good performances (Australia WC). That didn't legitimise his selection at the time and Wales' performance on Friday shouldn't necessarily legitimise Howley's.
McFadden, Gilroy, Conway etc getting game time in Japan ahead of the young lads is a very real fear for me. McFadden seemingly gets selected when fit and while playing Gilroy, Conway, TOH, might seem progressive we all know in the big games hell would have to freeze over for them to get picked.
