This head-to-head matchup keeps probabilities tightly bunched, reflecting both teams' dominant March Madness runs, elite seeding, defensive prowess, and path to the championship game, where the victor holds a clear edge. No. 3 Illinois (18%), fresh off defeating Iowa, and No. 2 UConn (13%), who held off Michigan State in the Sweet 16, trail as lower seeds facing each other in the other semi, underscoring the competitive bracket dynamics with upset potential lingering.
