Mike Gundy has added three assistants and two analysts to complete his coaching staff for the 2015 season.
Greg Adkins, Marcus Arroyo and Jason McEndoo have joined Oklahoma State's staff as assistant coaches. Their official job titles will be released at a later date, but FootballScoop.com reported Adkins had accepted a job as the offensive line coach for the Cowboys.
Gundy was looking to replace receivers coach Jason Ray, offensive line coach Bob Connelly and running backs coach Jemal Singleton. Singleton left for Arkansas on Wednesday, Connelly left for Southern California earlier this month and Ray was let go in January after two seasons.
Adkins coached under Doug Marrone as the tight ends coach for the Buffalo Bills the last two seasons and at Syracuse from 2009-12, where he coached the offensive line.
Arroyo comes to OSU after serving as the quarterbacks coach for the Tampa Bay Buccanneers in 2014 and as the offensive coordinator and outside receivers coach for Southern Miss in 2013. Before that, he was the quarterbacks coach and passing game coordinator for California in 2011 and 2012.
McEndoo was the offensive line coach at Montana State from 2003-14 and was named the FCS Assistant Coach of the Year in 2011. Montana State won the Big Sky Conference five times during McEndoo's time on staff.
Former Oklahoma State defensive coordinator (01-04) Bill Clay also joined the staff as an analyst. He last coached at Blinn College in 2011, where he was the defensive coordinator.
Former Kansas (2010) and Texas (2013) co-offensive coordinator Darrell Wyatt also joined the staff as an analyst. He coached wide receivers at Texas from 2011-13 and was the co-recruiting coordinator in 2011 and 2012.
