Your "Plains" division is much, much stronger than the "Lakes" currently. Also, with the success that Wisc., NW, Iowa, PSU, and NE have all had since 1993 (remember that's the date we're going back to), I really think you just handed the "Lakes" division to OSU. The only two teams have accomplished much since '93, and currently Mich. isn't there. Purdue has shown greatness, but faded. Illinois hasn't been good for years. Minnesota hasn't been relevant in decades. And MSU just can't seem to get over the hump, even though they've been beating "big brother" as of late.
I would say PSU goes "Lakes," Minn "Plains," at the least.
