Yeah, the player pool bit is concerning me.
We've got a lot of talent in the prem, but how much does White/Jones know about them?
Jones' comments about England in the World Cup seemed to suggest a certain vagueness on the score. White's probably watched scouting footage of Quins at least.
No reason they can't learn quickly enough I guess but there's still probably going to be a bit of trial and error at best.
