The defining moment of the first day of the 2018 NCAA tournament was, at once, fantastic and foreseeable. No. 11 seed Loyola-Chicago was a popular pick to upset No. 6 Miami at American Airlines Center in Dallas on Thursday. The Ramblers had already won at Florida in December. They rated out as one of the top 25 defenses in the country, according to Ken Pomeroy’s adjusted efficiency. They had rolled through the Missouri Valley Conference with only one loss since early January. Loyola-Chicago may be a little-known mid-major, but it did not stun the college hoops world by beating the Hurricanes.
