I don't need to lose time answering this in detail. God knows it certainly doesn't deserve it on any account because it's just so far from anything founded and interesting, but also because I can offer some element of response quickly: you've seen France play, at least a couple of games from 2013 til today. You've watched a bit of Top 14, surely stretches here and there if not full matches (as you rightfully should as a basic necessity, making such claims). So you know what Fofana, Picamoles, Parra, Dusautoir, Nyanga, Maestri, Kayser, Bastareaud, Dulin, Fickou, Huget...etc...etc...etc...are capable of doing on a functional team. Put two and two together. Voilà .
And I'm not hiding behind that concept we just don't have the coach while we should be dominant with a good one, but I know the players I talk about, I know them like my pocket, and I've seen what they can do against the best. With a proper coach, we could really scare the likes of NZ and SA, no doubt whatsoever. Just look at the recent results we've achieved against those two with *ZERO ATTACKING PLAN* and each player playing hero ball on his own initiative.
Here's a piece of patience from my part: the 'too many foreigners' argument is already age old and obsolete, the reasons have been stated literally dozens of times on this very forum, by me alone - and others. If you're truly committed to this topic, look for the facts, don't base yourself on false notions that make sense in theory but that are far from the realities.
