The Plaque in the Park

I found this little plaque, almost overgrown, on the ground in a park near my house.

It says, "Gus Williams, Coach of the Super Arcadia Teams. A Friend, Coach and Father to his Players. Started Coaching in 1912, Continued until the 1930's."

I wonder if the husbands in the neighborhood realized who the father of all players was. And why they all looked sort of alike.
