College Basketball Final Four tiers: Ranking the preseason Top 25 by their chances to reach final weekend

Key Points:

• The preseason AP Top 25 college basketball poll for 2026-27 features Florida, Duke, Illinois, and UConn as the top four teams and national title favorites, with rankings expected to fluctuate due to eligibility questions for key players on several teams.
• Kansas (No. 17) and Texas Tech (No. 19) could become top-10 contenders if their players seeking extra eligibility are cleared to play, potentially challenging for conference titles.
• The top-tier "S Tier" teams—Florida, Duke, Illinois, and UConn—are highlighted for their strong rosters, depth, and returning talent, positioning them as clear Final Four and national championship favorites.
• The "A Tier" includes Arizona, Michigan State, Texas, Tennessee, Louisville, Arkansas, Kansas, and Texas Tech, with several teams relying on transfer additions and key players' eligibility to reach Final Four contention.
• Michigan, ranked No. 16 and reigning national champion, is in the "C Tier" due to coaching changes, injuries, and roster turnover, marking the first time since 2014 a defending champion is outside the preseason top 10.
