I'm not really sure if thats him in pic or not High Plains. I had the same thought. I noticed other Hall of Fame inductees were noted if accepted by someone else on their behalf. This picture wasn't. Not sure. If I remember correctly the field was already named Diddle Young Field when I was a young fellow there in the 70's. Now wishing I could find more out. Its kind of interesting. This is all I found researching, per texas six man coaches association.
