As things stand with out Academy, the way to look at it
Plyers who can hack it at Championship level: Phillips, Tanganga, Parrott (which is where I rate the lower half of the Eredivisie)
Players who can hack it at League One level: Scarlett, Devine (who bossed it at Port Vale, not so much Plymouth)
Players who can hack it at League One level: Craig, Keeley (who, in spite his lack of clean sheets, was clearly a level above Barnet), Ndombele
Of course, after that there's the level of the unknown: Lankshere, Donley, Lankshere, Santiago, Soonsup-Bell, Hall and Abbott all have potential up the wazoo, but how does that translate in reality? Not only is there the obvious step-up, but also the risk of a loan either wasting his time like Nile John at Charlton a couple of years back, or even actively reversing their development as we've seen with Jack Roles or Massimo Luongo
