The system allows them a patina of qualification respectability, but ultimately, with one or two breakthrough exceptions, they'll take who they want - not least as once there, they can enter anyone in an event they have the time for even if that time was NOT got at finals. Not unlike athletics, GB Swimming go hard on relays these days - to be fair, that brought 2 golds and a silver last Games, and several world golds to boot, and unlike UKA, GB swimming have overseen a general improvement.
Much depends on Peaty - so far, his return has not been electric, but it has been very encouraging, he's behind the new Chinese wunderkind, but already catching others like Fink off presumably limited work - my instinct is he'll be there or thereabouts next year, motivated by a unique threepeat opportunity. The sudden religious element in his motivation I prefer not to talk about...
If Peaty is there or thereabout then, even with wunderkind, both medley relays are absolutely back in the game, although America is much, much better for the mixed than last time. In addiition, barring calamity I expect GNR to qualify for 4 x 100 free M, and I think their times in 2023 are already good enough in all other relays. If that holds...
...I think GBR are gold medal favourites in 4 x 200 free, medal favourites in both medleys and M 4 x 100 free and a good outside bet in W 4 x 200 free
Richards, Scott, Guy and Dean are a pretty amazing quad to be able to bring on 200 free 100 free (probably swapping Burrus for Guy and possibly whittle for Scott) and 200 IM. Freya Anderson continues to have the tools, but perhaps not the mentals, to do clown stuff on 200 free, and is a super solid 100 free leg, especially in heats
Individually, apart from the above, it's hard to say - will Greenbank come back to his world class form? Will Kstie Shanahan and Freya Colbert kick on? Will one of the several good british 100 back girls break through into great?
