Best March Madness Bets for Round of 16 

The Sweet 16 presents plenty of great betting opportunities every year. But which are the absolute March Madness betting sites for this round in 2023? You can see our favorite college basketball picks below.

• #1 Alabama -359 vs. #5 San Diego State +274 – Some are calling for an upset here because San Diego is athletic and good defensively. We don’t see it, though, since Alabama ranks better in defensive metrics and certainly scores better than SDSU.
• #5 Miami +6.5 (-110) vs. #1 Houston -6.5 (-111) – The Hurricanes have the offense to keep pace with the Cougars, even if they don’t ultimately win. They’re shooting 54.1% from two-point range and 36.8% on threes so far in the tourney.
• #15 Princeton -9.5 (-109) vs. #6 Creighton +9.5 (-111) – Princeton played excellent defense against both Arizona and Missouri during wins. It has the defense to at least hang with the Bluejays and cover +9.5.
