Best Bets for NCAAB Games — March 15, 2026

The Big Ten Tournament championship gives us a heavyweight showdown between top-seeded Michigan and Purdue at the United Center in Chicago. Here's where we see value in Sunday's title game. For more information, visit our NCAAB page.

Michigan at Purdue — 3:30 PM ET | Big Ten Tournament Championship

Michigan (31-2) has dominated the Big Ten all season and cruised through the tournament bracket, while Purdue (26-8) has battled its way to the championship game as a lower seed. The Wolverines have won both regular-season meetings this year, including a 78-67 victory in West Lafayette and a 71-60 home win in Ann Arbor. Michigan enters as the clear favorite to cut down the nets and secure the automatic bid, though they've already locked up a No. 1 seed in the NCAA Tournament regardless of Sunday's outcome.

**Injuries:**

• 🔴 L.J. Cason (Michigan) — OUT, torn right ACL (averaged 8.4 PPG, 2.4 APG off bench)
• 🟢 Purdue — full roster available, no reported injuries

Pick: Under 150.5 — The total has dropped three points from its 153.5 opener, and the market is sending a clear signal. Michigan's defense has been elite all season, and in their two head-to-head matchups with Purdue this year, they've held the Boilermakers to 67 and 60 points, respectively, while playing at a deliberate pace. Conference tournament championship games historically trend lower-scoring due to familiarity and defensive intensity, and with Michigan controlling tempo and Purdue needing to grind possessions, this sets up for a final in the mid-140s range.
