Ricco,
Just to help you out here. Pav was youngster when he came to the club. Ditto Haselby. Ditto Fyfe, Sandi, Elvis...ditto, ditto, ditto.
Every great player started out as a kid who needed games to develop. You could probably count all the champions for other clubs as well. No games, no development.
But, and here's where you struggle, they won't all develop into champions. Suban is a case in point.
The thing is, you never know if you never develop them and you never develop them by leaving them out of the side and playing known failures as a preference. You know, like Suban, Sutcliffe and the spack.
Playing the kids to develop them is not a myth. Playing the same old stagers because they are going to win you a game certainly is.
