Well, a case could be made that any absolute claims regarding Rog's actual feelings on the matter are purely speculative, no matter the conclusion.
He said years ago he'd be happy to see Kuss win a GT, i.e. for example there was an interview during one of his victorious Vueltas in which he clearly stated he'd be pleased if Kuss won, although "he needs the legs to do so" (words to that effect).
And Rog is a professional as well. These riders all face the exact same reality: when a teammate has the jersey (& more importantly good enough legs to defend it), you don't attack him. This is literally a basic rule of cycling. And Jumbo are even bigger on the whole "win together" mantra, so there will be no attacks from anyone.
That's all dandy of course but as a spectacle it's complete sh*t & I feel as fans we're perfectly entitled to say A/ "hey, I'd rather my guy won" & B/ "this race is tripe". I mean the prospect of the three Jumbos riding the last week in formation like a training ride & maintaining their current position... is bleak.
It's all Evenepoel's fault of course, i.e. "if only" he'd maintained a proper challenge we wouldn't be facing this non-race right now.
