Are we talking one year here...he did say post 1970 too.
I thought of Lynn and Rice but they would pale in comparison...different era though for sure....Best rookie combo though for sure.
Belle and Thomas had some years but from what I recall one or the other was having an off year when they were together.
Off the top of my head from 1970 onward...
1971 Stargell and Clemente come to mind, they won it all that year and both were great , Stargell was MVP like with 48 HR and Clemente had a phenomenal post season (WS MVP) and batted .341 in reg season
