The only thing I can think of is that maybe she is doing what I have done with my kids. They might be totally set on a college. But, I make them take at least one or two other visits to have something to compare it to.
The thing is, he has already been through the entire recruiting process before he signed with Wisconsin.
Things change every year. Coaches, assistants, rosters, depth chart.... I am too lazy to see where he took OV's and UOV's last year but maybe these are new schools he is looking at.
Plus it's only 2 schools he is visiting as he plans to enroll by the end of the week.
