Clubsthat won more than they “should” have tended to drift back towards the pack,whereas ones that looked cursed mostly got their just deserts later on.
我感觉看作一般过去时不太适合。
你断句错误，误以为主句是目前完成时。其实主句和从句都是一般过去时。than they “should” have是比较分句，该分句省略了实意动词won, 补全则为than theyshould have won. 主句的主谓结构是：Clubs tended to ...。that wonmore than they “should” have 是主语clubs的定语从句。whereas引导对比状语从句，从句谓语为一般过去时got their just deserts...。
