It depends on the year and the schedule.
Beyond wins and losses is the quality of the product on the field. What would be better, a 7-3 yawn of a win vs. SDSU to open the season or a competitive opening loss to say Oregon of the 42-38 variety? Well, a loss is never good, but I know which game would be more enjoyable to watch and would bode well for the rest of the season, and it sure as hell isn’t the former.
I think that’s the part of the W/L discussion that gets overlooked. Yeah, great, Iowa beat Nebraska by 3 points, but they laid an egg during the bowl game.
