Oklahoma State got off to a spirited start, forcing four Milwaukee turnovers and hitting 6 of 8 in the first 4 minutes to build a 15-5 advantage. The hosts led by as much as 21 and took a 44-27 into halftime. The Panthers committed 13 turnovers and the hosts were credited with 10 steals.

Cobbins, a 6-foot-8 senior, played in 13 games last season before an injury to an Achilles tendon put him on the sidelines; he was forced to sit out the first four games of 2014-15 due to an NCAA-imposed penalty for appearing in two games during a freshman season that eventually became a redshirt year. The Amarillo, Texas, product that averaged 5.6 points per game his first three seasons made an immediate impact, scoring the game's first four points and altering a Panther shot on their first possession.
