Twenty years ago, BC was a job that you could win some years. I'm not sure that is the case now. In 2015, BC was the only school that voted against increasing the student athlete stipend in a 79-1 vote and they have been late to fully fund revenue sharing. And, their NIL infrastructure is lacking and it doesn't seem they are 100% in. Fan support has collapsed.
If I were Murray, I would go to a mid major school that has a winning culture. You win for a couple of years, gain some expereince as a head coach, and you can move to better job than BC.
