Best Bets for NCAAB Games — March 28, 2026

March Madness reaches the Final Four stage with two elite programs battling for a championship game berth. Both matchups feature contrasting styles and postseason-tested rosters. For more information, visit our NCAAB page.

Iowa vs Illinois — 5:00 pm ET | NCAAB

This Big Ten heavyweight clash pits two programs seeking their first Final Four victories in decades against each other. Iowa enters riding an offensive surge that saw them average 82.4 points across their first four tournament games, while Illinois has leaned on elite perimeter defense to reach this stage. The Hawkeyes hold a 1-1 season series edge, including a 79-74 victory in the Big Ten Tournament semifinals, where they shot 51% from the field.

Pick: Over (when line is posted) — Iowa's tempo-heavy approach and Illinois's secondary scoring struggles create optimal conditions for a high-possession game. The Hawkeyes rank 18th nationally in adjusted tempo and have cleared 75 points in 9 of their last 11 games. Illinois counters with defensive discipline but has allowed 72+ points in three of four tournament contests when facing elite offensive efficiency. Expect both teams to push pace in this neutral-court environment, favoring the total regardless of where oddsmakers set the number.
