I wouldn't say i am being harsh, there is evidence of the more athletic lads struggling once they get to actual mens football, look at Solanke, Palmer & Izzy Brown....all big lads, towered over there opposition and won everything at youth level, they move up and they cant rely on there physicality as much and they struggle.
As i said before though, it is whats required in todays Premier League, physicality, athleticism & pace comes before skill and reading the game.
But what do i know, im just an arl arse who thinks everything that is new is rubbish
