I think this is a dumb move, because of 3 reasons.
1. Even tho Donie has stagnated this year and I kinda agree he probably can use another year at u23 level, it is very important that you keep Widar happy, and Milan is one of his best friends. He needs his friends around him to perform (and definitely if you want to have even a super small chance of keeping him after 2027). I would prefer Donie another year as u23 and Eeman (who is way more ready and also a very close friend of Jarno) to go up already.
2. If you just keep all these guys in your devo one more year, you're about to have like 8 neopros in 2027, which is just stupid and asking for problems. Not just the Lotto guys who already have that contract, but think about Van Bylen, Cuylits, Eeman, Taillieu (who's finally sickness/injury free and is making steps), etc. All guys who have proven to have enough talent to go pro, and you don't want to risk another Fretin. This is from a Lotto perspective ofc, I think Wanty has a bit less talents in their u23 that don't have a pro contract already (so not thinking about Gualdi or Kristoff, who even tho he's very talented I wouldn't really invest in as a team cause he will be at UNO X quickly anyways). I like Dolven (but also Norwegian) and Solen, but that's basically it right now imo.
3. I don't see a reason for keeping older riders who are not WT worthy anyways over them.
For Belgian cycling in general it will be very important that Flanders Baloise and hopefully also Wagner (less chance imo) find other sponsors so they can continue cause there's to much Belgian talent that's gonna go to waste without them. For example I think of Poelvoorde, De Ceuster, Vaneeckhoutte, etc. from Lotto, all 3 guys who have proven to have pro talent, or Hannes or Place from intermarché.
Also about the merger, whatever it's going to be Girmay just needs to make the decision, either stay or leave. Cause Bourlart needs to stop wasting his time on him if he's gonna leave anyways. Others are waiting, and it's taking way too long. You're risking losing way more than just Girmay. For example Rex, who's imo a key. De Lie needs him around him. It would be a massive fail from Bourlart already if he can't keep him imo. These are his guys, everyone tells me everyone loves him at the team, that he's a really good manager, but that wouldn't be a good look. And them I'm not even talking about someone like Barré who will definitely have a lot of interest. Thijssen ain't leaving, I don't believe that for a sec, he won't have better options and also said himself that he's 95% sure he will be at the merged team, he's just looking out for a plan B.
