Sadly, TdF 2022 did not really tell us anything about Primoz‘ exact shape, and the level he would have been able to achieve in the race, had he not crashed. His Vuelta 2022 got destroyed by the consequences of this crash.
I guess Primoz would have been on a similar level to Jonas in the TdF 2022. For 2023, if Primoz should ride the TdF (which I‘m sure of), to me it‘s clear that Primoz won‘t be Plan B or a domestique to Jonas. Primoz and Jonas then will be co-leaders on an equal level, getting both the same support.
Jonas had a very, very high level in TdF 2022. Certainly best ever GT performance. Fastest TdF ever. Extremely strong on all terrain. Primoz in top shape is on exactly the same level.
Primoz‘ masterpiece GT wise was Vuelta 2021. Starting with 2021‘s Vuelta, and even improving this level, he will wxactly be on the level of Jonas and Tadej. No doubt about it.
Roglic was not good enough in PDBF TT 2020, and had bad luck in Tours 2021 and 2022. If he reaches top shapefor July 2023, and stays away from bad luck, he clearly will go for TdF victory in 2023. He hasn‘t won TdF yet - Jonas and Pog already have. That will give Primoz this extra kick of motivation he will need.
He comes back to the TdF again and again, tries and tries. In the end, he could win the Tour. He IMHO has best chances, and Jonas and Jumbo certainly still consider him an equal leader to Jonas. Jumbo needs them both. Vinge and Rog vs Pog and Ayuso vs Super Remco. Sounds good, to me…
