I think that's fair, I would just say that's a general rule more than a French specific thing though. Like Dragan Bender falls into, for example. Killian Hayes, probably not though he was putting up numbers for Ulm and that was a big part of his case. Anyways, I think that's a legitimate question mark. It's fair to question Bilal on the basis of his low production/his rawness. I don't think saying he's overrated because he's French makes much sense and it's such a poor argument when there are much more obvious concerns.
Being French/Playing in the French league, is not a real knock on Bilal. That was the point of contention. If your argument is production-centric, I do not disagree. In fact, I've been saying that is the real argument against Bilal. What I disagree with is specifically knocking him because he's French, whatever is meant by that. I feel like it's really digging to try to force some connection to Bilal-Hayes, for example, when Bilal is raw as hell. The weirdness in this whole "French = Overrated" thing is that you don't have to dig deep to find question marks about Bilal.
