I don't see problem here, Marchisio and Gio were loaned and after good season they came back and played for us, the same thing is happening with Rugani. If those youngsters were any good they would stay with us. It's not like we sent them to a third world country to be slaves.
We are trying to sign as many as we can, but also we don't know how many of them will turn good. Masi was promising, but than he had a knee injury and vanished, so it was logical to give up on him for now, and focus on a player that might have better potential. We are betting on youngsters in hope that we will win one of those bets, but let's be real and acknowledge that it's impossible to predict development of the players. Remember Matteo Ferrari, Bonera and few other from Parma, they were the next big thing and all of them turned to be shit. I highly doubt that if they came through our system or Roma's or anyone else they would be any better than they are.
