That's a good point. Leinster have done a good job of replenishing their team though. Take the 2009 Heineken Cup winning team:
Nacewa, Horgan, O'Driscoll, D'arcy, Fitzgerald, Sexton, Whitaker, Healy, Jackman, Wright, Cullen, O'Kelly, Elsom, Jennings, Heaslip
Horgan, Whitaker, Jackman, Wright, O'Kelly and Elsom have already been replaced successfully. Sexton will be a big loss. O'Driscoll, D'arcy and Cullen will have to be replaced too. While they'll be very tough to replace, countering that, Kearney, Fitzgerald, Healy, Strauss/Cronin, O'Brien, McLaughlin and Heaslip are only entering their prime. The academy is churning out talent although a lot of academy players are moving on to other teams too.
Long term Leinster will be fine. Short term this will hurt. I think Leinster will take a backward step next season but they're still good enough to make at least the Heineken Cup last eight.
