Oklahoma State Officially Announces 2025 Coaching Staff

Through various reports throughout this early part of the offseason, the Cowboys’ new-look coaching staff started to become known. Well, now it’s all official — with a few names who haven’t yet been reported on.

Oklahoma State on Wednesday officially announced Mike Gundy’s staff for the 2025 football season. Here it is:

Theron Aych is a new name to know, as he is set to coach OSU’s wide receivers. He was a quality control analyst at Marshall last season and has previously coached wide receivers at Central Missouri (2004-07), UTEP (2016 and 2021) and Arizona (2017-20). Aych also has offensive coordinator experience, calling the offensives at Mesabi Range CC (1997), Angelo State (2011-15) and Tennessee State (2022-23). It looks like Aych will also have some help in that receiver room, with offensive coordinator Doug Meacham also being listed as the Cowboys’ inside receivers coach — a position he most recently coached at TCU.

Greg Brown is set to coach the Cowboys’ safeties after being an analyst for the Pokes last season. Before that, Brown was an analyst at USC. He’s coached a lot of football over the years, starting as a graduate assistant at UTEP during the 1981 season. He has a ton of NFL experience, as well, coaching defensive backs for the Atlanta Falcons (1994 and 2000-01), San Diego Chargers (1995-96), Tennessee Oilers (1997-98), San Francisco 49ers (1999) and New Orleans Saints (2002-05). At the Division-I college level, Brown has coached secondary members at Wyoming (1997-88), Purdue (1989-90) Colorado (2006-09), Alabama (2013), Louisville (2014-15), Missouri (2016), Auburn (2017-18) and Purdue (2019-20). He also has DC experience, calling the defenses at Arizona (2010), Colorado (2011-12) and Charlotte (2022). Tons of experience at all levels.

Despite being in Stillwater last season, Brown will have some familiarity with new OSU defensive coordinator Todd Grantham, as Brown was on Grantham’s staff at Louisville.

Sean Snyder is the only position coach from last season’s staff to remain in place, as he’ll enter Year 2 of coaching OSU’s specialists.

OSU also updated its support staff, which features Gunnar Gundy, a former quarterback at OSU and Mike Gundy’s son, as an offensive quality control coach. Gunnar spent three seasons as a quarterback at Oklahoma State, throwing for 449 yards and four touchdowns in nine games. He transferred to Emporia State ahead of last season where he led the Hornets to a 7-4 record, throwing for 2,751 yards and 23 touchdowns while running for another 299 yards and five scores.

Gunnar joins fellow program alums like David Glidden, Tracin Wallace, J.W. Walsh and Zach Allen on the support staff. Those four were all on the staff last season, staying in place despite all the changes around them.
