Yes.
P.S. And not just that. Even at Tour 2022. He was the deciding factor on stage 11. All while riding with his back broken. Then in contention again at Vuelta 22. Rogla is a proven two GT per year champion. Not only a participant in one and doing the other one seriously. ATM i am not aware about another cyclist in the pro peloton i could say that about.
If the "two GT podiums in a year, twice" thing had happened at an earlier point in his career - and been more recently - I would have agreed with you that it would be a good indicator for the potential of even bigger things. However, as things stand right now, time is not exactly on his side. He's not likely to win two GTs next year, and the further ahead in time we go, the less likely it becomes; he turns 35 in two years, how many GTs do you think he's gonna win past that?
