Truly, the nacional has always been poorly organized, ever since I was a kid it was a shadow of what it shoulda been. That's argentinian rugby for you.
Well, I have to say that it's no surprise Hindú just won. Amazing team, they always do stuff worth watching, exept in their finals, all the finals I've watched from them were awful.
About Pro D12/ SR:
-The main point of SR is not to prove Argentina is in fact a Tier 1 nation, but rather show Argentina can produce SR players consistently: that has been shown. SR has validated a very long effort by UAR, which is PladAR. From the first generation of pladars like Landajo, then Matera, Montero and so on till Ezcurra, Delguy and etc, pladar and the people who work there have shown their structure is functional and world class. That is huge in itself.
Still, so much to learn to be on the same grounds as England or NZ.
-Apart from that, yes, pro D12 is a more gradual step for the Jaguares, but I think they would outgrown it too fast: Jaguares is basically Argentina with some changes. I'm sorry, but Pro D12 is not enough of a league for a team like that.
Cheers
