I get your point, but he was sitting weirdly deep both on that previous mountain finish ayuso won and on today's stage 11. I don't think that's reflecting a deliberate choice of playing the long game. He just isn't at 100 % right now. Here's hoping for a strong last week, which is still more likely than not imo.
There are a few things going on here. First: he doesn't need to crash and have injuries add limitation to his and Bora's serious goals. When Ayuso went, it was around a bend and UAE guys screened the attack: Primoz's mistake for not being in that tight mix of guys. As it played out, he barely exerted himself to bridge to the second group and it worked as he and RB would have wanted. The optics might have been alarming to fans expecting him to slug out sprints; but it's not time for that yet. It wasn't today, either.
Bora is operating without their legitimate, strong #2 guy who crashed out. The others appear to be underprepared for week 1. Jai Hindley would've been in the GC mix requiring strategic attention from UAE and others. Not to mention he was one of the guys that could pace a climb leadout until Primoz moved and almost no one would be on his wheel. That asset is not in play. Time to adjust.
If you're the DS you have to strategize with the assets remaining. Primoz is doing his bit and not closing out on these minor time advances as he needs UAE to take pack responsibility. UAE knows that, but
don't really know what will come. The last TT Primoz rode very conservatively after warmup showed the course/conditions limitations he should observe. He did that and he beat every GC guy that counted. Now UAE has to consider who is their chosen lead assailant and what happens when PR is in a move with them? Is he hurt?
Every other team is in opportunity mode and who does UAE respond to? Carapaz is now fired up.
Bora's strategy is pragmatic with the talent left. It's their job to make the most of it.
As the Icon, Pogacar is uniquely intimidating to everyone. Would he be that guy if his top climbing support was gone, early in week 1 of a GT? UAE can't count on him. No other team really matters to Bora at this point. See everyone in week 3.
PS: posted this after the same observations all. It doesn't matter strategically whether he's weakened by efforts to date or playing weak. Both give the team time to respond later. Or not: it's likely to get crazy.
