I think Crees and/or Kay would be able to do decently in the elite race, considering the number of stronger riders that are taking part in the U23 race instead, and they've already been cheated out of doing the Euros this season. Kay did finish 17th last year, and out of those that beat her there, we know that Verdonschot, Rochette and Honsinger won't be there this time around and that Casasola might not be either, but I guess it was easier (and cheaper) not to field anyone among the elites.
That said, Kay did beat Franck and Fouquenet in Tábor, and it's definitely not a given that she would do that again this year, but a top 20 should still be within reach (Franck isn't riding, but Julie Browers has a similar level). Mason and Mein aren't looking like they'll be able to do much better than that, but Mason should probably still get the benefit of the doubt regarding his future potential.
You could of course argue that the third placed rider in the WC standings shouldn't be riding the U23 race (although she obviously isn't the third best rider in the World (yet)), but that is a different discussion.
