In general, and not speaking to or about Farrar specifically here, kids who make less emotional, business-like decisions -- not normally categorized in the recruiting lingo "blown away" -- tend to make the better students and happier, more invested and more dedicated student-athletes at ND. Success at ND in all aspects of life usually follows those, as they buy in, and the more emotionally fleeting "blown away" types often are the ones we come to discuss later on on these sites in less than flattering terms. Just the nature of the beast, especially at ND.
It doesn't matter whether Farrar is "blown away" by a visit. It matters that he views and has evaluated ND as the best option for him over the next four, if not forty, years. We'll find out soon on the latter, regardless of whatever the former may or may not mean.
