How is that even surprising. Like, no joke, we're top 4 without a doubt only behind the best team in the world (Germany), the last Champion (Spain) and the locals (Brazil), the fact that the last one was pretty average in the last years except in the Confed Cup is prolly why we're above them.
Rojo is called simply because we don't have a better 3 (although, Ansaldi, Casco or Insua could had been better options, who knows). We might not have the biggest names in our defense atm but who has, really? And, even with all that, Sabella likes to play with 5 in the back sometimes (yeah, I bet none of you knew that).
And no, Enzo is barely in the 23, he took Banega's place.

But seeing Rojo being called ... not that i watched many Sporting's games, but i think i always got the idea the guy is average, not that he is gonna play or anything, but still XD
TL;DR of everything you said: the players I've watched are pretty good, but I think that Rojo (who I didn't actually watch) is bad (even though apparently Real Madrid, Barcelona and Liverpool want him), so Argentina is bad.

And about the bet365 thing, it's obviously because we have a really easy draw and we prolly won't play against anyone decent till top 8. Spain might be out in first round, and if they're 2nd they'll play against Brazil. Germany has to beat you guys first, then play against (very likely) either Russia or Belgium.
