No, I'm saying that a straight percentage of how many years he's made the playoffs is a dumb way to evaluate a GM's tenure.
So, like advanced metrics, let's just invent a way to measure something in order to arrive at the results we want to achieve?
Rizzo just had BABIP his first 3 years...
What explains these past 2 then?
If a player is what the back of his bubblegum card says, what is the measure of the GM...only the good years?
