The top question will determine each Sweet 16 game in the NCAA Tournament is how the teams compete, with national title winners John Calipari, Rick Pitino, and Tom Izzo representing non-title winners such as Arkansas, St. John's, and UConn. All but two of these coaches were ranked in our preseason ranking of the Top 25 And 1 college basketball coaches. The top question is whether Texas can keep off the free-throw line, which Texas does, at 25.7 per game, while Purdue attempts just 17.1 free throws per game. Iowa must limit its turnovers to fewer than 12, and Nebraska is 15-1 when forcing 12+ turnovers this season. Key questions include whether Alabama can make 15 triples against Michigan and whether Solomon Ball can return to form after a scoreless game since UConn's 2024 national title win.
