Below is a snapshot of current market prices along with my top picks for these Final Four games.
- Illinois vs. UConn prediction: UConn to Win (45%)
- UConn presents solid value at a 45% implied probability, especially given their experience and efficiency on both ends of the floor. They’ve consistently executed in high-pressure spots and bring a balanced attack that can adapt to different game scripts. If UConn controls tempo and limits second-chance opportunities, they have a strong path to outperform this price and secure the win.
- Michigan vs. Arizona prediction: Michigan to win (53%)
- Michigan looks like a strong position at a 53% implied probability, backed by their ability to control pace and execute in half-court sets. They’ve shown consistency on both ends, with disciplined shot selection and the ability to limit mistakes in key moments. If Michigan can dictate tempo and keep Arizona out of transition, they have a clear path to justifying this price and coming away with the win.
