I think the point is we know they are good based on their performance on the field. You don't blow teams out like we've been doing at a college football level if you aren't good. But are we great? That won't be answered until we play the likes of Air Force and TCU.
I have no argument that Utah is at least good. Utah fans bitching because they dropped a point after blowing out a bunch of crappy teams... that's homerism. I agree, let's at least wait until they face AF and especially TCU.
