It's simple - let's imagine that B-I-N-G-O are replaced by "C (catcher) - CI (1b & 3b) - MI (2b & SS) - OF (all outfield) - P (both starting and relief), so C-CI-MI-OF-P
Now, generate five predictions for each position for MINOR league players this year (pick an easy one for MI for your free space).
Now, we could either (a) use our own cards, or (b) post all of the predictions, and I'll randomize them and assign a "playing card" for everyone who wants to play. Option "b" keeps it fair, so that some people's predictions aren't too easy and other's too hard.
At the end of the year, the community members win one of those cool minorleagueball caps or pint glasses or whatever, I'll buy 'em for the winners!
Anyone want to play? Maybe, if it's popular, it can even become a thing around here...
