To use a pitcher example:
Pedro Martinez had probably the greatest peak of any pitcher in history. If ranking peak value, he's probably #1. Sandy Koufax had a great peak as well, and is certainly near the top.
If ranking career value, well, Pedro falls behind, say, Nolan Ryan, who doesn't have much of a peak but pitched double the innings. Koufax would be behind both of them.
For an overall ranking, I'd rank Pedro over Ryan, but Ryan over Koufax.
