Level of competition is a legitimate thing to consider(both positive and negative), but I don't think the French league is bad enough to where you shouldn't be able to just scout the player. The French league is at the very least as good as pretty much any college conference in the US IMO. You should be able to just sit down and make a determination about positives and negatives, what projects well, what doesn't, etc. If Bilal doesn't pan out it will be because of things that are already there for everyone to see on his tape - lack of aggression, lack of offensive polish, off the dribble game, questionable shot, etc. If you don't think he can improve enough in those areas, you are absolutely justified in thinking he will bust. The fact that he's lacking all those things in the French league specifically doesn't add much IMO.
It’s just wild to me that so many prospects from the French League have busted massively. Just purely on odds alone one or two should have hit.
