Keeper decline vs Outfielders

[AAGunner3]

So when do keepers begin to lose their edge?
We all know that 30 yr old outfielders start the decline but popular perception has it that keepers don't hit their prime till later. So, when?

I'd thought outfielders begin to lose it at Age 28, and keepers at Age 30.

scoring goes down at 27 i believe, but defending starts to go down bit later. keepers are i think the longest lasting players. my random guess is probably around 31.

On www.hottrick.org it says they go down at 30.
