Yes, BYU needs style points to be considered for the Playoff, and at least some style points for the NY6.

However, you're setting yourself up for misery if you can't be satisfied with a season full of single-digit wins. If BYU is really one of the top 4 teams in the country, the big wins will come by themselves. If they don't - don't sweat it. Nothing's worse than criticizing your team because it's winning, but not looking impressive enough.
