Planning structured analysis
I'm thinking about the need to clarify various unknowns like age eligibility cutoffs, foreign and overage players, and reserve team integration. I’ll aim to keep the final answer structured in concise bullet points. I might consider adding a short header like "要点解读."
I want to ensure we don't assume specific details but rather list likely impacts and what clubs should watch for in terms of training loads and medical coordination. Delivering everything in Chinese sounds fitting for the user!

这是个挺重要的梯队竞赛调整。基于你给的信息,我先做个要点解读和可能影响,方便你快速判断关切点:
要点解读

潜在影响
待明确关键信息(决定实际落地效果)

给俱乐部/学院的建议

如果你关注的是某个队/城市或想看对比海外同类联赛(如英超PL2、德U19/U21)做法,我可以按你的场景给到更具体的策略和模板。你更想了解哪块:赛制细节、球员培养、还是运营安排?
