But what is weird is his visit is scheduled for after his commitment. I think that could be a positive or negative. Positive-he wants to commit to IU even without seeing it. Negative-He plans on still committing to KU and just going to visit IU after he commits.
Would IU keep the visit if he announced he committed to UK? Granted, means nothing until signed and he could change after seeing IU, but it has a feel of a "free trip" only if he publicly commits elsewhere, so I'd consider having a "we appreciate your interest but if you're committed elsewhere, we'll free up that spot for someone else" mentality from IU.
