In theoretical terms, yes. In practical terms, no. I don't know the exact structure of the Quins one, but the London Irish Developing Player Programme looks at a couple of hundred boys at U14-16, with around 10 automatically carried forward each year (the others are invited to trial again each time), and the list trims down quite sharply as they get into the Silver and Gold DPP (the equivalent of our EPDG)

Unless it's changed in the last 5 years Quins is different to Irish (whose system I'd heard about) Quins would cherry pick boys to look at throughout the season. If they saw something in a game, (Jim Evans and Howard Graham went to loads of games to view players in the EPDG and those of interest who weren't). It did'nt matter what position you played or how many were already in the EPDG, if you piqued their interest you were invited along to the EPDG. You might only last 2-3 Monday nights once they got to work with you but if they thought you had potential to make it as a pro then you were kept around until the 'final' decision at 18.
