So, I was just looking at the windows to win championships. It looks like the majority of the time, there's about a five to nine year period that cores have from the first time that the reach the finals to the time that they have a last hurrah and make it back to the Finals. Seems like there's always a mix of established vets, guys in their prime and rookies.
