Just in the Big XII alone, Haliburton, Likele, Dotson, and Butler all have higher efficiency numbers than Coleman. I'll give MC credit for developing into a really solid shooter. He was a very below average shooter coming out of high school. I want to say he shot at or near 20% from 3 in the EYBL games.
I have an issue with the stats because they think all stats are equal.
Stats are only as good as the data you use in basketball. They still need to work on it.
