The biggest cover margins of the season — the games where the spread was most spectacularly wrong.
Xavier was a 2.5-point home favorite — the market's way of saying the teams were functionally equivalent with a home court edge. Creighton won 98–57. A 41-point final margin on a 2.5-point spread produces a 43.5-point cover.
What makes this different from a simple blowout: the market had genuine uncertainty about which team was better. That uncertainty resolved emphatically, in one direction, 98 to 57.
Gonzaga, a 3.5-point road favorite at Michigan, lost 61–101. A 40-point loss on a 3.5-point spread is a 43.5-point cover margin — tied with Creighton–Xavier for the season's largest.
The same Gonzaga program also appears in the upsets list for losing to Portland as a 22.5-point road favorite. Two losses months apart that together paint a portrait of extreme variance.
Louisiana Tech was a 2.5-point road favorite at Delaware — a market essentially calling the teams equal with a slight edge to LT. They won 81–38. A 43-point road victory on a 2.5-point spread produces a 40.5-point cover. The market saw two teams separated by almost nothing; the game said they were separated by 43 points.
Marist, a 4.5-point home favorite in MAAC play, beat Iona 83–38. A 45-point final margin on a 4.5-point spread produces a 40.5-point cover. The line said this was a competitive game between two programs in the same conference. It was not competitive.
NC State was a 4.5-point road favorite at Florida State — a modest line that respected FSU's home court. NC State scored 113 and won by 44, covering by 39.5 on the road. Florida State scored 69. NC State covered by nearly 40 on a road trip where the spread said they'd win by 4.
Northern Illinois, a 3.5-point home favorite, lost 64–99 to Lindenwood — a program the market deemed slightly inferior. Lindenwood scored 99 on the road. NIU would appear on this list twice more, always as the team on the wrong side of a massive cover margin.
Northern Illinois's second appearance: a 1.5-point home favorite against Ball State, losing 43–79. NIU scored 43 points — one of the lowest outputs by a home team listed as the favorite all season. Ball State covered by 37.5 on the road.
Central Michigan, a 4.5-point home favorite, beat Northern Illinois 88–46. NIU scored 46 — the third game on this list where the Huskies were on the wrong side of a 37+ point cover margin. CMU covered by 37.5 against the same program that also appears as the loser in ranks 6 and 7.
Eastern Michigan — which beat Cincinnati as a 22.5-point underdog in November — was a 2.5-point road favorite at rival Central Michigan. CMU won 100–65, covering by 37.5 as the home dog. The same team that appeared in the upsets list was itself on the wrong side of a 37.5-point cover margin a month later.
Utah Valley, a 7.5-point home favorite, beat Samford 89–45. A 44-point margin on a 7.5-point spread produces a 36.5-point cover — the largest cover margin by a favorite of 7.5 or more on this list. The market had UVU as the clear better team; the game confirmed it emphatically.
