Regarding TdF, I'm shocked to see Narvaez not doing it after his fantastic performance last year. Yates is regressing as a rider so I thought McNulty would be the obvious replacement to him.
Nevertheless, this won't matter at all. Yates can still be reliable in the mountains (not the last man anymore) and Pogacar won't need much help since I believe he will not have a single threat in the Tour.
Any gap under 6' will be a big surprise to me.
