Well, when you pick the oldest three guys ... you're going to wind up with a list of the oldest three guys.
Earnshaw's a solid starter at 32, which isn't particularly old by modern standards. We have at least three more strikers under 30 and Jordan Hamilton coming up as well, so there's a sort of logic to it, younger guys learn from older etc.
If they score, I could care less if they're 38.
If we had Earnshaw and Davies up top, with Koevermans and Davies playing alternating roles to keep them healthy, that would be a troublesome pairing in every game against any defence in this league.
In fact, you can sort of see where this is all heading now, which is a pretty immediately competitive team, but with key parts that will go soon, allowing them to bring down the overall age of the squad slowly at the same time as breeding a competitive tradition.
It's predicated on getting the right people, competitors and fit at any age, then having depth. No matter who we lose to injury, we still have one experienced finisher on the field, and have some quick, talented but inexperienced secondary strikers to slot into the position opened by injury.
