This is not a VT situation.
A) Nigel Munson decided to not go to VT after the horrible shooting episode AND having a pregnant girlfriend in DC.
B) The coach of VT believed that GW had tampered with Munson as they believed that GW had tampered with Wynton Witherspoon before that. That is what was motivated the limited release given to him.
As to Houston - I imagine that there is some possibility that Houston could stay. But don't confuse that with some notion that Houston is either a good coach OR a good recruiter, because he is neither. He adds VERY little to anybody other than a shot at getting Erik. If he stayed - it would be an awkward arranged marriage where everybody knew that the couple was going to be sleeping in different bedrooms from the start.
