Michigan-Arizona for all the marbles? What Final Four history says about ‘de facto title games’

Key Points:

• The NCAA Tournament's Final Four sometimes features the two best teams facing off in the semifinal rather than the championship game due to the lack of reseeding, as seen with the Arizona-Michigan matchup in the current tournament. Both teams are No. 1 seeds with dominant performances and top KenPom efficiency ratings.
• Historically, several Final Four semifinals have been considered de facto national championship games, such as Duke vs. Kentucky in 1966, NC State vs. UCLA in 1974, and Houston vs. Louisville in 1983, with varying outcomes where sometimes the semifinal winner went on to claim the title.
• Notable upsets and memorable games include NC State's double overtime win over UCLA in 1974 ending UCLA's dynasty, and Jim Valvano's underdog NC State team beating Houston's "Phi Slama Jama" in 1983, highlighting the unpredictability of the tournament.
• Other significant semifinal matchups like Indiana vs. UNLV (1987), UMass vs. Kentucky (1996), and Duke vs. UConn (2004) showcased intense competition and sometimes led to the semifinal winner capturing the national championship, while in other cases the other bracket's winner prevailed.
• Several honorable mentions include key matchups such as St. John’s vs. Georgetown (1985), Oklahoma vs. Arizona (1988), Duke vs. UNLV (1991), and Maryland vs. Kansas (2002), which were highly anticipated but did not always result in the semifinal winner becoming national champion.
