I was a SOM player myself in the late 60s, early 70s. We used to toss all the various card sets (seasons, past seasons, HOF, etc) into one big pile and draft multiple teams each. All-time greats along with our present-day (at the time) favorites. It was a fun (albeit not very accurate) way to learn about past baseball greats.
We did something similar called "the All-Crumbs" games. You would draft your opponent's team and you would have to do your best with the scraps he picked for you, sort of like an expansion draft.
I still remember Eddie Brinkman (Washington Senators) and Ray Oyler (Detroit Tigers), both great with the glove, but it was a banner year if they hit over .200.
The idea was to get even wear on the cards by letting everybody play.
