All of that stuff is subjective. The only way to fix college football is to go to a plus one system.
Sorry! But from an unbiased viewpoint (I'm not a fan of both schools), USC would beat Auburn 8 out of 10 times. SC is just too talented. Plus, they have grown as a team.
Now, unfortunately, we will never know for sure, but in watching both teams, clearly, USC is the dominant team.
