Why can't colleges get the info they need while player is on school visit? Why do they need to come into your home?

Knowledge is Power! Thank you Mavens and HSBBWEB!

They don't NEED to come into your home. They may choose to ask to come into your home because they want to talk to you in your comfort zone.

I think the bigger reason is that you cannot make an official visit until their school is in session in the Fall. If they want you badly, they need to get face-to-face with you as early as possible and that may be July. We had in home visits from schools on July 1, July 9 (two), and one in August. Our son had lots of options and so the coaches wanted to wrap it up as quickly as possible. They didn't want to wait until September (we made them wait anyways). They didn't want to wait until "official" visit timeframe.

Chicks,
My experience is similar to that of Justbaseball. They just want to visit with you and get a jump start before an official visit. And I think they want to check out the whole picture. If a school is going to invest in your son, they want to make sure it is worth it.
My son also waited until his official visits before he made up his mind.
