In the Starting Line-Up
Too lazy to search - wtf is a slappy?
You'd have to ask Ron Borges to sure how he was using it, but I took it as having a negative connotation. It's from a Boston Herald article that jmt57 quoted in post #6:
“Basically, I tried to point out all the great dynasties and all the people those teams have in the Hall. Now, you get to the Patriots. Is it one Hall of Famer (Ty Law), and 52 slappys?”
In that context, I'd interpret "slappys" to mean JAGs, nobodies, or anonymous players.
