As I showed above, when Michkov comes over at 21, Couts (34), Sanheim (30), TK (29) will be the oldest Flyers. Even teams that tank bring in older veterans when they deem the kids ready to compete (look at NJ with Hamilton, Palat, Haula). They will also have 21+ picks the next two drafts. So age distribution will not be an issue.
The biggest problem is filling the hole at center. They need a young two way physical center to pair with Frost, and I think that's where they may potentially package some draft assets. They can start a kid on the 3rd line with say Cates and Brink and give him time to develop. If they draft centers, they may not arrive until 2027-28 or so (2-3 years after draft). In that case, they might sign/trade for a veteran to be a 2-3 year stop gap, because Poehling/Laughton are not 3Cs.
