Best Bets for NCAA Tournament Games — March 21, 2026

Saturday's Sweet Sixteen slate features three No. 1 and No. 3 seeds looking to assert dominance, but tournament chaos has already claimed several favorites. Here's where the sharp value lies in three compelling second-round matchups. For more information, visit our NCAAB page.

(3) Illinois vs. (11) VCU — 7:50 p.m. ET | CBS

Illinois dominated its first-round opponent behind David Mirkovic's monster 29-point, 17-rebound performance, but now faces a VCU squad riding serious momentum after erasing a 16-point deficit to stun North Carolina in overtime. The Rams' havoc defense forces 16.8 turnovers per game (14th nationally), and Terrence Hill Jr. is playing at an All-American level with 34 points in the UNC upset. Illinois went just 4-6 ATS as double-digit favorites this season.

Pick: VCU +11.5 — Illinois struggled against elite defensive pressure all season, averaging 19.2% turnover rate against top-50 defenses compared to 14.1% against everyone else. VCU's "Havoc" system thrives in neutral-site tournament environments where Illinois can't rely on home-court advantages. The Rams are 9-3 ATS as underdogs this season, and Hill's 34-point eruption signals he's locked in. Lay the points with the live underdog getting nearly two possessions of cushion against a team that consistently plays down to competition.
