Yeah, I think you can view it 10 ways from Sunday...but here is what i think is the applicable rule. And, I know nuttin.
13.6.7.9 Activities During Official Visit. An institution may not arrange miscellaneous, personalized recruiting aids (e.g., personalized jerseys, personalized audio/video scoreboard presentations) and may not permit a prospective student-athlete to engage in any game-day simulations (e.g., running onto the field with the team during pregame introductions) during an official visit. Personalized recruiting aids include any decorative items and special additions to any location the prospective student-athlete will visit (e.g., hotel room, locker room, coach's office, conference room, arena) regardless of whether the items include the prospective student-athlete's name or picture.
