I don't think Leinster got caught up in their own hype, they are still a cracking team. LI were only slightly better and showed up Leinster at the lineout. Leinster should still come out of the group but may not have a home 1/4 final tie. Leinster have the required skill to go all the way again this year.
London Irish played better on the day; Leinster had the posession but couldn't turn it into points because LI kept the pressure on all the time. Leinster were far too defensive from the start and onlt showed real fire in the last 10 minutes.
I thought that Irish were just the stronger team on the day. It's not all over for Leinster, it's only the first game. I thought they really missed Rocky, any team would be weakened by his departure. They have to face up to Brieve next game and get a result but thats not beyond them.
Munster have had a shaky start too - Geraghty really cut through them - at least it wasn't a home tie though.
