My WAR calculation is a combination of Baseball-reference and Clay Davenport; I believe it to be the "best" WAR number available for historical comparison. 8 WAR is an MVP quality season. The record is pythagorean adjusted for 162 games.

-The worst stretch for Giants baseball in three decades continues here despite the return of a now 39 year old McCovey who passes Marichal on the all time WAR list. I dont remember the season with great clarity, I was 6, but this was my first Giants club. It's a wonder I kept going. Speier doesn't keep going, he leaves for a decade, but he'll be back.
