I understand what you're saying.
BUT, you shouldn't underestimate the France 98 NT and Zidane was out almost the entire tournament (red card against S. Arabia I think?). That NT was ridiculously talented. Skippers like Deschamps and Desailly, young hungry players like Thuram and Henry, Petit having a hell of a tournament, Lizarazu being one of the better left backs of his generation (bar Maldini and R. Carlos obviously), the creative genius of Djorkaeff in midfield, etc... Zidane decides the final on his own, yes, but the rest of the tournament it were the other guys. Credit where credit is due.
And the France 06 NT wasn't sh*t, come one Fiero. I remember that final distinctively, and just like Gattuso said in an interview a few months after that game, I was thinking the same: "Dayyum, those guys look huge and unbeatable, what the f*ck are we gonna do against THOSE guys?". Everytime Henry or Malouda got the ball, I was totally afraid of what was going to happen. Every. Single. Time. They looked so confident, dangerous and badass. Same goes for Zidane ofcourse, who looked untouchable, he was almost floating around the pitch, totally controlling the game. And then France also had Ribery, who wasn't the player he is now, but a diamond in the rough, everybody could see that. He was a constant attacking threat. They had the experience in the centre of the pitch with Thuram, Makelele, Gallas and Viera, and Abidal was rock solid those years. Not a bad team at all, on the contrary. Zidane was the undisputed leader, but again, he had an awesome team to lead.
Singlehandedly carried his team in those two WC's you say? I have some doubts. France was a force back then.
One of the greatest and unique players ever? Yes, defintely.
