Blake Seiler and Collin Klein spent last weekend at the side of new Kansas State football coach Chris Klieman as he wrapped up the early recruiting period.
On Friday, Klieman made them the first official hires to his Wildcat staff.
Seiler, who served as Bill Snyder's defensive coordinator in 2018, will coach the defensive line, while Klein will return for his third season as quarterbacks coach.
"I am pleased that Blake and Collin will remain a part of our staff here at Kansas State," Klieman said. "They both are tremendous young football coaches who I have had the chance to get to know over the last several weeks while recruiting, and they provide our program with some continuity and familiarity.
"As former Wildcat players, they bleed purple, and I am excited for what they will bring to our staff."
Seiler coached K-State's defensive ends from 2013-16, then switched to linebackers the following season. He added the defensive coordinator title this past season, leading a unit that ranked third in the Big 12 in scoring defense (25.4 points per game) and fourth in total defense (403.4 yards allowed) in the regular season.
Seiler, a Goddard native, played defensive end for K-State from 2003-06. After two years in the private sector, he returned to K-State as a quality control coach in 2009-10 and served as a defensive graduate assistant from 2011-12 before being promoted to full time.
Klein, a former Wildcat quarterback and 2012 Heisman Trophy finalist, started his coaching career at K-State in 2014 as an assistant recruiting director and spent the following season as an offensive graduate assistant. He then spent the 2016 season as quarterbacks coach at Northern Iowa before returning to K-State in 2017.
Klieman said Wednesday that he hoped to name the rest of his staff in the next week or so.
