With WSU and UNI both up by 14+ at halftime over the #3/4 teams in the Valley, I was starting to wonder if this might be the best top two separation in Valley history.
Obviously the Evansville loss for UNI means that the two teams will have to lose at least three games combined ... even if one of the two drops another game outside of the remaining UNI/WSU matchup, this would still likely be the most separation in modern Valley history.
2002-03 seems to be the closest, with SIU and Creighton combining for five losses, which UNI/WSU are almost guaranteed to at least tie at this point.
You'd have to go back to the 1959-60 season to find a year where the top two teams combined to only lose three total games ... they played 14 conference games then.
You'd have to go back to 1947-48 season to find a year where the top two teams combined to only lose two total games ... they played 10 conference games then, and there were only six teams in the conference.
In 1928-29, Washington went 7-0 and Creighton went 4-1 for a combined single loss. I have no idea what kind of ridiculous schedule they used to come up with one team playing seven games and one playing five, but there were five teams in the MVC that year.
From a pure winning % for the top two teams, UNI and WSU (91.67%) could have the highest combined separation from the rest of the Valley since the 1922-23 season, when Kansas & Missouri combined to go 30-2 against the rest of the conference (93.75%). The nine team Missouri Valley Conference went 6-6 out of conference that year, combined.
