Keep in mind that we were supposed to play UCF but they pulled out forcing us to replace them with Western Kentucky. UCF isn't a great opponent, but they're better than Western Kentucky.
Quality is a relative term. They aren't Miami or Florida State, but they're certainly better than Western Kentucky or Western Carolina.
What's more, if we're talking about the BCS (which we are), you have to realize that many of the computer polls simply look at the W/L record of the opponents, and although Hawaii's 11-3 isn't the same as an 11-3 Miami team, a computer might look at it the same way.
