Grandchildren will wear you out. There's no player today who compares to Bill Russell. As great as Shaq is, it would have been interesting to have Chamberlain knock bodies with him or Russell blocking all his shots. I mean, John Stockton is a hell of a player, but I don't take him ahead of Cousy. I never had a set of rules.
Every situation is different.
There are ways to gain an edge. It hangs up. In kickball, you water the field the night before or you let the grass grow. In hockey, you make soft ice if you're playing against a fast team. In baseball, you raise or lower the pitcher's mound according to your pitcher, not their pitcher.
