A little data analysis for you folks this AM:
Using KenPom archives, I took a look at every NCAA Champion's offensive & defensive rating midway through February. I found that of the last 25 championship winners, 92% met an offensive rating of at least 22 and a defensive rating of at least 43 midway through February. There are 14 current teams that meet this criteria: Auburn, Alabama, Florida, Duke, Houston, Purdue, Wisconsin, Texas Tech, Arizona,
Illinois, Iowa St., Clemson, Maryland & Marquette.
Further, 64% of champions met a offensive rating of at least 10 and a defensive rating of at least 43 as of the middle of February. There are 7 current teams that meet this criteria: Auburn, Alabama, Florida, Duke, Houston, Purdue, and Wisconsin. If Illinois plays very productive offense over the next two, they can be well into a top 10 offense (currently rated 15).
The table below shows winner, their ending Off/Def rating, their Feb Off/Def rating, and the total change from Feb to end of season.
