I've found a number of sources with information about specifc ages at which player peak and at which they decline (see Doug Drinen, Couch Potato, Football Outsiders - some links below).
Has anyone seen this information built into a formula showing an aging curve (a curve estimating improvement and decline in performance based on player age)?
I am trying to implement these numbers into an equation in Excel. I assume it's a relatively symmetric quadratic equation, but I admit my math isn't strong enough to pull that formula together quickly. So I thought I'd see if it already exists and not try to reinvent the wheel.
BTW, Couch Potato's Quality Years Remaining formula doesn't work for this purpose because it only show years left before a player declines.
