He had about a decade of assistant coaching (some of it at BYU), where his teams had decent but not overwhelming success. Then he went to UVU where his teams had decent but not overwhelming success. Then he came to BYU where his teams had...wait for it...decent but not overwhelming success.

I remain unconcerned about our next HC.
