All 14 Big Ten teams have now played at least 10 of their 20 conference games. That means, as of today, we’re halfway through the Big Ten season and officially one month away from the most glorious time of year. That makes this a fitting time to take stock — literally, in this case — of each of the conference’s teams. I’ll try not to focus too heavily on the NCAA Tournament, as we’ll be surely doing a lot of that in the coming weeks. We’ll see the true and final forms of these teams over their final 8-10 games of league play. But it’s no fun waiting until March to gauge their mettle. What else are weekly power rankings for?
