NCAA Tourney Scatterplot
The above chart plots each team by the average height and weight.
Oklahoma is closest to the average in terms of both measures.
Oklahoma State, however, are a bunch of bruisers, with a strong combination of height and weight.
Illinois is the tallest, but aren't shabby on weight either.
Eastern Kentucky is the shortest team on average, and are also the most 'compact' as a combination of height and weight. Since E KY has the short title, I'll give the official 'most compact' designation to SE Louisiana.
Alabama A&M was next shortest, but they don't matter anymore.
Iowa is the 'lankiest' team, in my view, with the an average combination of tall and lean. Syracuse and Pennsylvania are close behind in lankiness.
Finally, the most 'squat' team in my view is Niagara, but Georgia Tech and Minnesota are in the running.
I still don't have a methodology for picking the winners, although I'm still leaning heavily from going with a "Bruiser" wins method.
