if any really, perhaps fly-half ?...and even that honestly, Guy Camberabero, Jean-Pierre Romeu, Didier Camberabero, Mesnel, Penaud, Deylaud, "***ou" Lamaison, Michalak, Trinh-Duc and I'm by nooooo means a historian whatsoever, I focus on current Rugby, but those are names I've heard, read of, and just checked stats for and honestly they have a damn solid résumé, in world Rugby that is not just within borders.
As cocky as it may sound, because you know, French cock and all that; we may not really have a traditionally weak position. It's quite possible we don't, I don't have the knowledge to categorically say, or even make a case for it, but I can think of world class players throughout from all kinds of eras, and it's not like we're lacking anywhere today, if not somewhat, if any, the second row. But even that's not really true.
Maybe FrenchFan and gaston and Tony could throw in a few words and thoughts about this more accurately than me.
