Many, like my nephews from Arizona who attend there and didn't get accepted at BYU, love BYU sports and this helps give them a connection to BYU athletics even though they're at a different campus. They share the BYU name.
A couple of the Ohio State regional campuses in different parts of Ohio (not Columbus) do this as well, it is not a new idea.
Way to go IROC and BYUI - totally support this.
GO COUGS.
