Fogarty: It wasn't good enough and I won't sleep until we get the scrum right
The clamour for the next generation to be pushed through may come at a cost.
For example, Ireland international Tadhg Furlong went from the exposure of The Champions Cup to the relative rugby wilderness of the British & Irish Cup in the space of five days last week.
Just turned 23, the Wexford tight-head will have to rebuild from the base up, perhaps comforted by the knowledge that every world-class prop playing the game suffered before they succeeded.
It is simply a fact of any professional life. The only crime is not to learn from your mistakes.
The truth of the matter is that all four Leinster props paid the price for their inferiority against Wasps.
Like any front row forward, it is very difficult to recover when you start from a bad position.
"It wasn't good enough. There's no way of hiding from that," explained Leinster scrum coach Fogarty.
"They managed us early in the scrum from bind down to set. They chased a bit after set. We were just on our feet. Our alignment went off a little bit.
"That left us vulnerable to their snap, that weight coming through. We could put weight through ourselves, but not the right amount of weight, not effectively because of that.
"That is something we scouted before the game. It is disappointing and it's not good enough that we, as a group, didn't address that over the 80 minutes."
The technical flaws have to be ironed out in time to be ready for Ulster at the RDS on Friday night in what is fast-becoming the basket in which all of Leinster's eggs will be placed this season.
"I'm sure that supporters, when they see the game, they want to see that chest-out, fighting hard," he said.
"We're not looking to Friday. We're looking to today, this training session so that we can create an opportunity on Friday for this team, for our province, for our supporters.
"I'm not going to sleep until that happens. None of the players will either." Speaking of the players, full-back Rob Kearney (hamstring) should be available for Friday.
Seond row Hayden Triggs will probably get another week to recover from a rolled ankle.
The three concussion victims Sean O'Brien, Richardt Strauss and Mike McCarthy are in the process of the return-to-play protocols with the latter rated the most likely to return.
There could be an opening for a genuine seven in Josh van der Flier.
"The spark in the ruck for him to hit and chase, the unseen stuff maybe, he is exhibiting that.
"Maybe that is what we need, some of that."
