finetto and mooncalf were not signed because they do not have personal sponsors, in other words they are not paying for racing
I heard something like that about Finetto, but with the Venezuelan Federation sponsoring the team you'd think that they'd resign one of their strongest riders.
Speaking of Venezuelan Riders signing with Southeast, Yander Godoi has signed a contract with them for the rest of the season (he'll start racing with them in July).
I don't really know him as a rider and he's still young (born in 1993), but as far as I can see his best result was probably an 8th place on gc in the 2014 Vuelta Ciclista a Venezuela. Did they just sign him because he brings a sponsor/has a few friends in the Venezuelan Federation or is he actually a big talent?
