Your thread, your rules bruh ; )
I've read SO MANY conspiracy theories about what happened that day... I mean, it obviously affected the whole team, but I'm not sure if Brazil would've won, even if Ronaldo was fine. France ALWAYS "had Brazil's number", for quite a while now. Plus, they were playing at home, and Blatter was always a crook. But I'll never discredit France winning that title. They deserved it.
Oh, about the conspiracy, the "best" one I've ever heard was that Ronaldo found out that his then girlfriend (I forgot her name, it's the blond one that married Julio César - Inter Milan's former GK - some time later) was "fooling around" with a prestigious Brazilian reporter behind his back. After I heard about it, I remember thinking like, "it's not that absurd...". I also clearly remember (I was 19 years old at the time) that every single halftime of every game Brazil played (before the final, that is), there was the reporter dude (and he's always been famous for being a "womanizer") interviewing the girl. Seriously: EVERY. SINGLE. HALFTIME. And they were both real "mushy" with each other, it was noticeable. Ronaldo most likely found out somehow, or someone told him (or who knows? Maybe some teammate joked about it, and he took it seriously). He couldn't take it (he was very young, after all), probably snapped / freaked out, and then he convulsed...
It's obviously all hearsay, and as you, I don't think it's sensitive to bring back the subject, as Ronaldo is also one of my favorite players of all time. And he totally redeemed himself in 2002 with a memorable World Cup, so... It's all "barbershop talk" and kind of interesting, nevertheless.
