I don't have any access to BC's contract, but I imagine that there is a cancellation fee on our side of the contract too. So if A&M decides to cancel their visit to Conte, BC is potentially inline to collect that money.
In the end I imagine this will be settled between the Athletic Departments. I don't think much or any money will change hands. What's surprising is that A&M is so adamant about this. As I've pointed out many times, College Sports is a small world. Usually both sides would try to settle this behind the scenes and amicably.
