Best March Madness Picks for Today’s Round of 64

Here are my top Round of 64 picks for today’s March Madness slate. Be sure to sign up with the best sportsbook promos for March Madness to maximize value on these plays, or explore additional 2026 NCAA Tournament expert picks for more betting insight.

• Tennessee vs. Miami (OH) prediction: Miami (OH) moneyline (+350).
  • Miami (OH) is a strong value underdog because of its disciplined half-court offense and ability to limit mistakes. They play at a controlled pace, which can neutralize Tennessee’s athleticism and prevent the game from turning into a transition-heavy matchup. If Miami (OH) can knock down perimeter shots and avoid turnovers, they have a realistic path to keeping this game close and pulling off the upset. In a single-elimination setting where variance is high, getting +350 value on a team with structure and composure makes this a worthwhile play.
• Clemson vs. Iowa prediction: Clemson moneyline (+110).
  • Clemson presents value as a slight underdog thanks to its defensive consistency and ability to dictate tempo. Iowa typically thrives in faster, offense-driven games, but Clemson’s physical defense and disciplined rotations can disrupt that rhythm and force tougher possessions. Offensively, Clemson is efficient in the half court and doesn’t rely on high-variance shot selection, which gives them a steadier floor. In a matchup that could come down to execution late, Clemson’s balance and composure make the +110 moneyline a strong pick.
