Yes, the Davis girls are identical twins. The video said they were 6'2", but I don't think they are quite that tall. They both went on to play for Clemson. Susan Starnes was another key player on that team. She later played for Tusculum College, a local school, and is in their Hall of Fame (if I'm not mistaken).
The Davis girls both teach and coach in the Greene County school system. Jennifer's daughter is a freshman on SG #53. I saw her play last week. She's special.
The South Greene community is like a large family. Many of the past players come to the games with their families. Several current players have parents that once played for SG. It's great going to the games.
