Ok maybe not pull but the coaches should not plan on him. If you are going to take a look then you are not committed and the coaches should have that policy and many if them do.
"Listen, if you visit another school, we are going to move forward with our plans as you are not committed."
If the Bussey situation was say a huge position of need.. Let's say quarterback. And he made it known that he will decommit if you recruit another QB. Then he takes visits to 3 other schools, what are the coaches expected to do? Be committed to a kid that doesn't show that commitment back? Its a two way street.
