RBH wants to become a team with many victories. To do that, they definitely need another sprinter. Meeus and van Poppel, who isn't actually intended to be a sprinter, can win, but they don't win very often. You need a fast finisher, especially for smaller races. Let's see if that will be Donati from the Rookies or if they will look elsewhere. In general, I'm really excited to see which rookies will get a place. Some riders deserve a chance. However, according to Denk, there aren't many expiring contracts in the WT-team.
In addition to Thornley, Jasch, Donati, Boichis, and Tuckwell also deserve it, as the team probably has a special fondness for him since he was the first rider to sign with the Rookies.
As for the rest of the riders, I don't think they're ready (yet) for the WT team, or they're still so young that I'd rather see them stay with the rookies until 2026 with a few appearances in the WT team (e.g., Finn).
