In case you want, you can watch the entire season 2013 on youtube, if you do want, I can find the link and post it (if it's legal, sure).
I haven't been lucky enough to watch 2014, which is pretty bad because there are Pumas prospect to follow, not just Cordero, but also Patricio Fernández, Sebastián Poet, Lucas Maguire (I think he already had a ride with the Pumas), Juan Cruz González, etc. Also, Felipe Contepomi came back last year, I think Todeschini still plays with his hometeam once in a while... and of course, the Pumas Montero, Landajo, González Iglesias.
From what I can remember from last year, rythm is slower (not as much as many people would believe), there are many handling mistakes, and obviously the organization is poor if you compare it to a pro league, but the main thing is physical. All of those things depend on the oxigen the guys have: the handling mistakes come in the last period of the match, when they are exhausted and out of breath; at the beginning happens because the're too audacious, silly mistakes you can see at any level. The organization is based more on individual tackles rather than schemes, because in that way you don't depend on the condition of the players in the last quarter of of the match, and I think CUBA is the perfect example of this: they commit all of these mistakes, they have a very risky stile if you wish (depending too much on their contrary to produce points, not necessarely dominating territory...).
I wish anybody could tell me about a very good amateur (properly casted) league so I could compare it to URBA (and interior, obviously); I think is one of the best amateurs in the world.
