This was one of the stages JV could make Ineos work. Due to demonstration on stage 4, people expectations in this thread, it was rather obvious, before the stage started, JV had already won the stage 6 and Roglič got the bonification seconds, wasn't it?
In the end that made Ineos work, well before stage 15, and JV was smart to capitalize on that. Additionally only JV knows, when they will lunch an attack. It is reasonable to expect, some sort of an attack will happen before stage 15, but nobody knows when. That makes other teams nervous and that makes other teams work.
At the same time JV doesn't have to defend maillot jaune, for an addition of 10 days, compared to some other rival teams! And for people after saying, they faded in week 3. Obviously, if you are killing yourself, and your team, for 2 weeks, when biggest rivals sit behind and rather do nothing, there is a bigger chance you will have fatigue issues in week 3.
For the people expecting Roglič will fade in week 3, you put too much emphasize on Giro 2019. He lost his stomach, due to bad nutrition, breathing hurt, due to hurting his chest in a crash, and he still finished on podium. That doesn't read as fading to me.
All well and good, only Ineos didn't work. That was precisely the problem. They rode a comfortable, middling tempo so as not to expend any helpers all the way up. And everybody else fell into line behind them. If Castroviejo was going deep and swung off and Ineos were expending domestiques and people like Kwiatkowski and Carapaz were being burned off, you'd be right and Jumbo would be playing a smart long game. If Ineos were setting a tempo that was burning off secondary and tertiary contenders, or at least getting rid of career domestiques like Cherel and Reichenbach, then you'd be right and Jumbo would not come in for the criticism they have because Ineos would be doing a job to make the race, maybe not in the most exciting fashion but as much as we can expect in week 1 (this would be
actual attrition). But Ineos were soft-pedalling and everybody else was happy to let them. If Bernal was feeling bad and that was all he could muster, then that's fine. But I can't believe that other teams didn't notice Ineos' tempo was false based on power meters, the time gap to the break etc., and if not one, not a single solitary rider or DS on one of the other major teams thought "this tempo is false, I wonder if Bernal isn't feeling too good, maybe we should spend a couple of kilometres at pace to find out?" then the racing mindset is even worse than I thought. Because if it turns out Bernal is fine, you just lay it off and accept it didn't work. If it works, then you've nothing to lose. If nothing else it's a psychological shot across the bow. And if your hold on the race is so tenuous that a couple of kilometres of exploratory high tempo on stage 6 will cost you, you aren't a serious contender anyway and are the kind of rider that a stronger tempo would have dropped.
And why do people forget that you aren't forced to try to lead the race start to finish if you don't want to, you can ship the maillot jaune to a breakaway if you don't want to defend it for three weeks? Before the latest generation of superteams, it used to happen all the time. Let the break get a dozen minutes up the road today, and say to the sprinters teams, we're fine with this, don't mind losing the maillot jaune as we're playing the long game, and if you want to sprint it out, you'll have to do the pacing yourselves. It used to make breakaways more interesting too, because you'd have people fighting out for opportunities to get into the lead, and then trying to defend strong GC positions afterward. Christ, in 2009,
that Astana team with Armstrong, Contador, Klöden, Leipheimer and Zubeldia in it were happy to not chase and let Ag2r hold the maillot jaune for a week, and even THEN they tried to ship it to a breakaway on stage 14 to save themselves the effort the following day, only for the in-fighting between Garmin and HTC to cause the bid to get Hincapie a day in yellow to fail. In the 2008 Vuelta, you even had some intrigue built around this, because Astana were letting a breakaway go, which would have put Egoi Martínez in the leaders' jersey. Caisse d'Epargne wanted Astana to keep the jersey because it could foster discontent between Contador (the nominal leader) and Leipheimer (the race leader), so they toasted their domestiques to try to keep Astana in the lead (unsuccessfully). However, that they did this then angered Euskaltel so when Valverde was caught behind a split in the Suancés stage, they helped Astana make the pace at the front to distance him, and apart from Purito who was in the front group, Caisse toasted all their domestiques behind trying to bring Valverde back after he lost his mind and started trying to chase back across on his own.
