Santa Clara is closer to home for Brock, but not exactly commuting distance. It's an 11 hour drive and a 2 hour flight.

Considering the fact that he is giving up a $6,000/year FCOA stipend, I can't imagine he will get home much more than he would at Liberty. My guess is this move was made more for basketball and other reasons. Brock should be far and away the best player and the centerpiece of that team from day one. He has also said he questioned his choice to be an aviation major and was going to change to something less demanding even if he had stayed at LU.
