The Leinster branch deserve a lot of credit for identifying and helping develop talented young players. As said in my previous post, I don't think it's right to name individual schools and under 18 club players in a public forum but I'd say there are around 10 players in senior cycle (4th - 6th year) in Leinster to be very excited about.
Looking at the success Leinster had from 2008-2014, Leinster may have rested on their laurels a bit (Munster too from their period of success in 2006-2011). As the top talents were being replaced, inferior players were being brought in in the expectation that they were good enough. Little by little, the team weakened. My hope is that with the Leinster academy churning out players, this won't be allowed happen again. The biggest threat is clubs with more money offering Leinster players contracts too good to turn down.
EDIT - a huge talent was lost to Aussie Rules last year; Conor Nash. 6'5" tall fullback who came through the club route with skills and pace to burn. Hopefully Leinster keep in touch in case he changes his mind. Only 19.
