Erm, hang on...'gone on to be good/great players'? I get full on what you are doing, good idea, but gone that description is wrong. Ha.
Maybe gone on to 'make it' might be better...Ruddy and Mustafi for sure.
Gosling was a flop. Vaughan has done well at a lower level. Baxter did well at an even lower level. Lukas has made a name for himself but again at a lower level.
Other than Ruddy and Mustafi, no one is missed.
