This should be a concern for Italy. Parisse, Castro, Zanni, Canale, Masi are all of a similar age and will retire at similar times. If you look closely at their side, the core of it has been together a long while now, right back from when John Kirwan was in charge.
Meanwhile, their junior side has lost to Georgia and Japan within the 12 months, and has been relegated to the secondary IRB Junior World Trophy after losing to the Pacific Islanders junior teams Samoa and Fiji as well.
And their fly half problems are over a decade old, Orquera is 31 now, and they seem to have given up actually producing a 10 of their own and are just flying in Argentine/Australian/South African rejects to be their 10 such as Burton, Orquera, Botes or di Bernardo. None of whom would challenge getting in any other Tier 1 sides B team.
It´s true, but last weekend Italy´s u20 tied with Ireland´s team... 25-25 with four tries to three. Actually, their results in this u20 6 Nations are not as bad, and similar to the french results...
Italy U20s 6 - 13 France U20s
Scotland U20s 30 - 17 Italy U20s
France U20s 13 - 27 Wales U20s
Italy U20s 10 - 25 Wales U20s
England U20s 40 - 10 France U20s
Ireland U20s 22 - 5 France U20s
England U20s 52 - 7 Italy U20s
Italy U20s 25 - 25 Ireland U20s
France U20s 13 - 10 Scotland U20s
Does it mean France need to worry about their future? Of course not. The results of a generation alone are not really important, either they´re bad as you say or quite good (for Italy) as last u20 6 Nations.
You´re right about the end of the retirement of the backbone of the team... But the same could be said about a lot of players and Italy kept improving. Think about the last time you saw Mauro Bergamasco, Marco Bortolami, Mirco Bergamasco, Perugini, Ongaro, Festuccia, Agüero, Del Fava, Dellape, Sole... In fact, from the great forwards pack who won two games in the 2007 6N, Castrogiovanni (31), Parisse (29) and Ghiraldini (28) are the last survivors, as Lo Cicero is retired now. Since then, Cittadini, Barbieri, Favaro, Pavanello, Minto, Geldenhuys... had been added to the team, and the pack is consistent. But it´s true Parisse can´t be replaced, even if Barbieri is in great form and Mbanda looks good.
The change in the backs has been the same, or better, and I´m sure Italy has now the best backs they have had in a lot of time And most of them are youngs... Think on Gori, Venditti, Benvenuti, McLean, Sgarbi... Canale is not as important now, he played 5 minutes against France (Castro didn´t play against Ireland either). The centers in the victory against France and the good matches in November were Benvenuti and Sgarbi. Masi is still crucial, but McLean has played well as fullback.
And there are some good prospects, as Angelo Esposito (fullback/wing), Morisi (center), Campagnaro (center), Iannone (wing)...
Fly half is a black hole, it´s true. But it has been the same since the retirement of DomÃnguez, so italian rugby is used to
. It´s not true either they have given up to produce a fly half. Actually you have to be italian or be able to play for Italy in order to play as fly half in the italian league, and now there´s a program to try to develop some fly halfs from utility backs as Paolo Buso, but I don´t see much future there...
In the u20s Padovani has been the 10 for ages, but it´s very similar to Orquera, but even worse kicker, so it´s not going to be easy for him to reach the NT.
