If the camp is open for anyone/coach to come watch and it's reasonable/possible for the other coach to attend, I don't see why not. The idea of providing the schedule to targets is to give them as many possible dates to choose from to schedule time to come see the prospect. Having said that, I'd put "7/16/21 - University of X Prospect Camp" and call it good. I wouldn't put "7/16/21 - University of X Prospect Camp, Coach Johnson personally invited me to attend" The coaches will see the camp listed there and connect the dots. And if they want to truly know the interest level of University of X, they'll ask you straight up. IMO there's a very fine line between skillfully building your brand/leveraging legit interest and overtly boasting/trying to "work it." Coaches want to feel loved as well. In this climate, I'd argue VERY few kids hold any leverage whatsoever over a prospective coach. Most can afford to select the players that truly want to be in their program the most.
