His average conference finish is 6.3. If you took out his first year, its 5.8.
Averages like this are really bunk science though. Fran's first year and 2017 stinkers weigh down the average by a full point. A lot of coaches have seasons like Fran's 2017. Matt Painter went 15-17 in his 9th season. John Beilein went 16-16 in his 8th. Thad Matta went 17-15 in his final season. These are outlier years that might be chalked up to bad luck more than anything, but they really hurt average W/L and conference finish.
Regardless, a 5th-6th place conference finish isn't stupendous but its by no means bad, especially since we play in a 14-team league. It means we're statistically above average.
