I just did some pondering.
Let's get slightly back on topic, and let's not.
I'm not sure if Nibali's crash in the 2018 Tour matters THAT much (in terms of just that race at least). Even if (big if) Nibali wins that Tour, I don't think it changes his legacy all that much, nor Froome's.
It's kind of weird that once Froome became a force at the Tour, he raced it seven times, and out of the six times that he finished, he was only beaten once by a rider not on his own team (and that didn't hurt or mean as much because Thomas was in yellow).
And it was never very interesting, and not necessarily because of Froome. We had some years when Froome was definitely very good, but also where Nibali was very good, and Quintana was pretty good, and Contador was at least still pretty good; but for one reason or another, the aftermath of "Let's get ready to rumble!" was always a disappointment.
It's ridiculous that in the end, the best we were left with was Contador and Froome, recovering from injuries, fighting it out for the THIRD biggest GT.
We had riders such as Uran and Bardet coming closest to Froome in July. Somewhat sickening.
Having skipped his home GT in 2014 and 2015, Nibali kind of had to go back to the Giro, I suppose. And nobody wants to be the focus too much on July rider. But Vincenzo was the one guy who could have seriously challenged Froome in 2016, and maybe 2017. I'm adamant that his legs were good in 2015, but that he was just a week or two late in timing his preparation. PSM was a major stuff up (should have been his usual Dauphne display). He couldn't have gone with Froome that day, but he should have been able to keep Porte and Quintana in his sights, and then maybe we have a race. And 2016 and 2017 Froome wasn't as dominant imo.
