Before you lock in any 2022 NCAA Tournament picks or build any college basketball parlays for Thursday's Sweet 16 games, you really HAVE TO see whom SportsLine's top college basketball expert, Larry Hartstein, is backing.

A former lead writer for Covers and The Linemakers, Hartstein combines a vast network of Vegas sources with an analytical approach he honed while working for Pro Football Focus. Hartstein has dominated college basketball, going 366-311-13 ATS since March 1, 2020, for a profit of $2,323.

And in his last 151 against-the-spread picks in college basketball, Hartstein is an outstanding 88-61-3, returning $2,093 to $100 bettors. Anyone who has followed him is WAY UP.

Hartstein has locked in his confident picks for Thursday's four Sweet 16 games, and he has a parlay that would pay more than 12-1. We can reveal one part of the parlay: He is leaning toward Duke (+1) covering against Texas Tech (9:39 p.m. ET). "Texas Tech's 'no middle' defense is the nation's toughest to solve, but Duke has the personnel to do it," he says.

Hartstein also has locked in three other spread picks, including one best bet on a team that he says has "yet to play their best game." You ABSOLUTELY need to see these picks before locking in any 2022 NCAA Tournament picks or college basketball parlays of your own.
