Sweet 16 Matchups to Trade On
Kalshi offers markets for all four Sweet 16 games on Thursday:
- Texas vs. Purdue – 7:10 p.m. ET on CBS
- Expert Pick: Under 146.5 (49%): Sean Miller and Matt Painter, tied for eighth among active Division I coaches with 25 NCAA Tournament wins, have both built strong defenses that have carried their teams to the Sweet 16. With a week to prepare, I trust Texas can contain Braden Smith and track Fletcher Loyer, while Purdue’s perimeter defenders can pressure Texas’ wings, so my pick is Under 146.5.
- Iowa vs. Nebraska – 7:30 p.m. ET on TBS/truTV
- Expert Pick: Iowa +2.5 (55%): Nebraska opened as a 2-point favorite with a 134.5 total, but Iowa’s lockdown defense and ability to make timely shots give them a strong chance to keep it close and pull off a late win. Considering Nebraska’s struggles from deep and Iowa’s defensive toughness, my pick is Iowa +2.5.
- Arkansas vs. Arizona – 9:45 p.m. ET on CBS
- Expert Pick: Arizona -8.5 (46%): John Calipari’s Arkansas faces a tough matchup against Arizona, as the Razorbacks’ struggles defending the rim, controlling the boards, and limited depth make covering the 8.5-point spread unlikely. With Arizona’s physical, opportunistic style and ability to exploit Arkansas’s weaknesses, I’m taking Arizona -8.5.
- Illinois vs. Houston – 10:05 p.m. ET on TBS/truTV
- Expert Pick: Illinois ML (42%): Despite Houston’s home-court advantage and elite defense, their struggles defending the perimeter and reliance on rebounding make containing Illinois a major challenge. I like the Illini to exploit these weaknesses and pull off the upset, so my pick is Illinois ML.
