yes - but they have a lot more.
Why are you concerned about rebuilds with only Sidey, Pendles and Howe as the only elites over 30yo in 2021?
Because you need succession in place before they drop off a cliff so the team doesn't. Also depends on how you rate the list, is it a flag or multi flag worthy list? is it only a middling list competing but maybe not quite there or only capable of "pinching one"?
Many reasons to look into the potential for a rebuild or "renovation" if you will over the next 2-3 years.
