I'm pretty sure it's his own wish to captain in the Giro rather than domestique in the Tour.
Obviously, he couldn't demand to lead or co-lead in the Tour. There's no f*cking him over going on.
Jumbo have loved their multiple leader thing to death, I think it's very weird if Roglic can't get a protected spot if he wants one.
Maybe this is a shift in priorities. They got their Tour, maybe they're no longer as obsessed about absolutely maximizing Vingegaards chance to win another, especially after he was simply stronger than Pogacar on the climbs this year. They were also expressing an interest in winning the Giro before coming out with the schedules.
I don't think Roglic was really playing media games either. Just a few weak statements to wait for the scheduling announcement. He was clear about wanting to give the Giro a shot but not being in a rush as he thinks he has a number of good years left.
I don't really doubt he can be ready by the Giro, considering he's training now.
For me the biggest surprise is actually not going Giro/Tour but now probably going Giro/Vuelta. But that might have been Roglic personal preference.
