The biggest change was on defense, where defensive coordinator Bill Young was replaced by Glenn Spencer, who spent last season coaching linebackers at OSU.
Young told the Tulsa World when he left that the move was made, in part, to help recruiting.
“He thought my age would hurt recruiting and he thought players wouldn't play for me,” Young told the paper then, referencing Cowboys coach Mike Gundy.
Clements was considered one of the best recruiters on the staff when he was at Kansas State. The other top recruiter on that staff, Michael Smith, left after last season to take a similar job in the SEC at Arkansas.
The Cowboys also went young and energetic with Yurcich, who is not yet 40 and came to OSU after serving as the offensive coordinator for Division II Shippensburg.
