Not to cast dispersions on anyone's prophetic powers or mysterious implied insider info. but it is just irrational to suggest that Vanderdoes is on the verge of committing to anyone at this point.
He opened up his commitment because he wants to explore the aternative open to him more carefully. He might well like the manner in which one staff or another has recrutied him. He might well be thinking he would like to play for this coach or attend this school based on his limited understanding. But he clearly has not made up his mind and his visits are going to determine wher he will ultimately commit.
He has many factors to consider. I think it is logical to conclude that since he considers academics a fairly high priority, Notre Dame has a good chance. He has also indicated that distance from home is not a major factor, that is great too. If he is not too turned off by the weather, everything else about a visit to ND cannot but help our chances. Who doesn't feel inspired when they are standing in front of touchdown Jesus, or slapping the sign, or entering the stadium? Who doesn't feel in awe while at the Grotto? How can a player not feel how special the place is, if they are not already a hater? If he likes what he knows about Notre Dame, I like our chances once he experiences the place.
