I'd say I know a couple of kids that I think COULD have accepted offers as Freshman, but as far as I know they did not. I've also known a few parents that WOULD have accepted an offer for their kid at about any age if it was made.
Not surprisingly, this includes the father that told me that he would spend any amount of money on his son's baseball because his son's baseball was going to support his retirement. His son had quit baseball before high school.
My wife and I spent quite a bit of time talking with our son before allowing him to commit in November of his Senior year...we were fine with the decision - just wanted to be sure that he understood what it meant, that he'd considered his options and make sure all of us were as comfortable with his decision as possible...Its always a bit of a gamble...Time will tell if it was the right decision for him...
