Limerick had a guy sent off early in the Munster final I think, so that would have affected it a bit. But decent display from Limerick, shows we are not so far away - but for a poor performance on the day it could / should have been us in the final.
But the main thing about underage is being up there, winning stuff is great, but being in or about it is good enough. Look at the footballers, one minor win in donkey's years but the best senior team in the country. But the minors have been there or there abouts in football most years (apart from the last two), if the hurlers can do the same (and they are), it will be fine.
