Hit and Run,
They could very well be nothing more than an invite to their camp.
My son attended two camps (Alabama and Mississippi State). I contacted both programs prior to paying for the camp. I got assistant coaches in both cases (but in the larger D-1s the assistants are the recruiting coordinators) and explained who I was. "I'm the father of (son's name)" and both said they had been following my son. It was obvious from the phone conversation they wanted to recruit him. I paid the money, he attended their camps, and ended up signing at another school.
