a loss.
There's no benefit to BYU.
I think that the costs are as follows:
- Potential loss given that UVU players could come into the game hyped out of their minds for the cross-town rivalry;
- Potential 'rivalry game' for UVU that could be used to spark school spirit and marginalize interest in BYU (minor point--but still exists).
There's no reason to play UVU. Why give them a reason to feel relevant?
