I don’t know that you have to run as much as bleed the play clock and use short passes as de facto runs. There’s just no excuse for blowing a 32-point lead.
Even short passes can be a bit of risk though. Incomplete passes stop the clock, passes can be intercepted.
Late in that game, WSU was backed up, had a 63-60 lead with just over 2 minutes left. They threw a short pass, the receiver fumbled the ball. UCLA recovered and was already in field goal range.
Not saying that a running back wouldn't have fumbled, but I think it's less likely.
I might be old school, but to me, a team needs to at least be able to run the ball enough to burn clock when necessary.
