In the nightcap, the No. 3 seed Arkansas Razorbacks meet the No. 1 seed Baylor Bears at 9:57 p.m. ET, also on CBS. Of the four teams, only Baylor won its regular-season conference championship.

Oregon State and Houston both won their conference tournaments. William Hill Sportsbook lists the Cougars as eight-point favorites and the Bears as 7.5-point favorites in the latest college basketball odds for the 2021 NCAA Tournament.

Top 2021 NCAA Tournament Elite Eight expert picks for Monday

One pick Severance is high on during Monday's 2021 NCAA Tournament Elite Eight schedule: Oregon State vs. Houston goes under 130 total points. These teams have leaned on their defenses during March Madness. Oregon State is allowing just 61.3 points per game in its three NCAA Tournament 2021 victories. The Cougars, meanwhile, haven't given up more than points 60 in any game during the Big Dance this year. 

Syracuse mustered just 46 points against Houston in the Sweet 16. Neither team loves to push the tempo, and Severance views this matchup staying under what is already the lowest total listed by William Hill for the entire Elite Eight. "This will be a rock fight and probably the lowest-scoring Elite Eight matchup," he told SportsLine.
