Basketball Team of Old

My sister found this picture of our father and basketball team for Park Rapids high school.    Dad is the 5th one from the coach, and his brother is behind him.  His brother John actually was a year older than dad, but both graduated together, I believe in 1927.  I have no idea who any of the other players are or the coach, so will be taking this picture to the "all class reunion committee" to see if they have any old pictures close to that year of graduation.  I wonder if they had numbers on their shirt backs?  Found it interesting that their shoes don't look like they give any support at all!
I remember hearing stories of how good an athlete my dad was; both in basketball and especially in football.  He wasn't that big, but must have had the spirit and aggressiveness needed to be good.
