Below is a table of the average RPI quality of each conference team's wins and losses (Source: Basketball State). As you can see, by this measure, Minnesota and Nebraska are very similar. Illinois and Indiana are virtually identical. Wisconsin has by far the highest average quality of its wins among the conference and Northwestern and Purdue are clearly the lowest. There's not nearly as much variation among average quality of teams' losses. Iowa has the highest average quality of losses followed closely by Michigan State. What's somewhat interesting about our scheduled second round opponent is that, although they've lost only half as many and have the most impressive set of wins in the conference, their average rating of opponents in losses is lower than ours. Minnesota calculated RPI rank by this source currently stands at 47.
