Your example is an ultra rare exception which is exactly my point.It's not out of the norm especially with parents that have dreams of their child being a D1 athlete. We had a girl that had a late September birthday. Her mother had dreams of the girl becoming a college softball player so they waited until she was 6 to enroll her in kindergarten. She was 7 the majority of her kindergarten year. She did go on to play college softball, but not at the D1 level.
