It'll make 2019 interesting.
Sky's modus operandi relies on the strength of the unit and the whole of that unit backing one rider, ok last year's TdF was a bit of an exception, but the riders will be aware that they may need to put themselves in the shop window. A number of riders who have recently negotiated loooong contracts aren't going to best pleased either, especially Ivan Sosa who has just blotted his copybook elsewhere to ride for Sky next year.
A further complication for both riders and the search for a sponsor will be the mooted changes to the number of WT teams, from 18 to 15, so riders are going to need points if they're searching for a contract. Mind you, UCI reforms have a long history of just getting kicked down the road.
There are also some complex rules about transferring points and licences between team entities, it used to be the case the licence was held by the management entity, and it was this and the contracts that gave the management entity value, I'm not sure that this still holds, but Sky was a bit unique in that the sponsor owned the management entity who owned the team.
