You can do the well they beat so and so and they beat so and so.....all day long by circular games. We did that one year having ETSU as National champions by virtue of them beating I think was NC state who beat Clemson who beat I for get but it went all way to the Natty winner had lost to one of the teams earlier in a chain of wins. Unfortunately it doesn't work that way every game takes on its own dynamics. It can be turnovers, it can be reffing, it can be injury to key player, bad coaching , a key player getting in a zone and on and on but every game takes on its own dynamic, what makes Football so interesting.
