Here is the thing....the SoS only matters (and I use this term loosely) in two situations:
A) First part of the season, before the conference play begins. It is only something to consider in terms of trying to assess a team's performance and its translation into Conference play. Sometimes, fans will go all crazy for a 3 - 0 team not realizing that the 3-0 team played patsies.
B) Secondly - it only really matters for teams competing for the playoff spot. If, and I mean if, somehow Arizona runs the table and goes undefeated....then YES, we can look back and question that out-of-conference schedule if that ultimately keeps Arizona out of the playoff.
But I would love for that controversy to happen, as that means the Cats ran the table.
At this point, SoS is meaningless. Conference play is here, and the whole mess of rankings etc... really does not matter. Each game now is about winning the PAC-12, and as a fan, I kind of ignore the whole rankings issue except as a matter of determining what other games to watch outside of the U of A.
