In absolute numbers, probably.
But when a franchise is able to import as many mercenaries as they like there is less incentive to develop local talent. It's a helluva lot easier to buy established names, probably better for the box office, too.
Short-termism is trumps in France, and the results were laid bare during the Cup.
Surely it's a compromise between multiple things.
They also have the Pro D2 and then the Federale 1 below that so there's quite a heirarchy of professional down to semi-professional competitions.
A pro competition that is essentially a franchise competition will always present some challenges to development because there will always be the ability to just buy players from the levels below.
The challenge for French rugby is to ensure they can generate enough money from the game to support the grass roots to enough of a degree. France came 6th in the 2014 U20s and 4th in 2015 so the development of their younger players isn't out of line with their expected international results.
France were atrocious in their quarter final but otherwise performed to expectations.
They didn't exceed expectations which they often do at RWCs.
How do their playing numbers relate? Is the Top 14 full of many famous players (albeit plenty past their prime) increasing the interest of rugby in France making it more attractive for juniors to take up or is it damaging it because the locals don't like watching foreign players play?
It's a problem if the French Rugby Union is expecting privately owned professional teams to do all their player development.
