IMO Walscheid's potential lies more in cobbled classics (mainly Paris-Roubaix) and potentially being a world class leadout man. His wattages are really high, but it's hard to built a sprint train for such a tall guy/find multiple guys that give him a decent slipstream to draft behind.Yeah that could be happening now although Kooij is the better prospect in my mind. But there are a lot of sprint options still there besides Jakobsen & Bora has the more valuable thing (a leadout) in place.
I think you have a better value to money trade off with Welsford. I don't think Ackermann is a target as he also moved away from pure sprinting and had the fallout with the Bora team. Mayrhofer and Walscheid would be to german options out of contract but they are not winning you GT sprints. So I think jakobsen is likely but maybe better to go for Welsford and use the rest of the Bennett money elsewhere. I think matt Walls experiment with WT racing will also come to a close so they could sign one of the german guys as secondary sprint option for smaller races.
With Healy of the market there are not that many targets there as well for a big upgrade on the classics/ mountain domestique front. Theres not a lot of Top 100 riders or big talents to sign. I see Tulett, Schmid and Vernon left as interesting targets. But we shouldn't forget that there are strong indications that they already signed Adria as a nice piece for one day races. If the colonel is an insider and they loose also Politt and Konrad they need some serious enforcements as there already weak spring racing squad looses there best performers of this year.
Welsford and Dainese are the cheaper options and I can see why they'd go for someone younger like Wesford. Dainese would be a good fit for a French team like Cofidis. They already have a few Italians and need a guy who can win gt sprints. You throw your money at either him or Jonathan Milan.
