Oklahoma State head basketball coach Mike Boynton has announced the non-conference portion of OSU's 2017-18 schedule, which will pit the Cowboys against four postseason squads, five RPI top-105 teams and three 20-win teams from a year ago.According to KenPom, the Cowboys faced the nation's toughest schedule in 2016-17, and the 2017-18 slate appears to be just as daunting with matchups against Florida State (Dec. 16, Orange Bowl Classic), Wichita State (Dec. 9, Stillwater), Arkansas (Jan. 27, Fayetteville), Tulsa (Dec. 19, Stillwater) and the 2017 Legends Classic field that includes Texas A&M, Pittsburgh and Penn State."Our goal will always be to put together a non-conference schedule that prepares our team to compete in the nation's toughest basketball conference while giving Cowboy fans an exciting slate of games they can look forward to, and I think we've done just that," Boynton said.

I'm excited for the upcoming season, and to have Gallagher-Iba Arena rocking again."The Cowboys will open the season with a three-game homestand that includes Pepperdine (Nov. 10), Charlotte (Nov. 13) and a regional matchup against Oral Roberts (Nov. 16).
