PROVO — How BYU football will be coached in the trenches came into focus Thursday when coach Kalani Sitake announced the hiring of three coaches to his staff.

Steve Kaufusi was named the defensive line coach, Mike Empey was tabbed as offensive line coach and Nu’u Tafisi was named the strength and conditioning coach.

“Establishing the line of scrimmage is very important and I’m confident Steve and Mike will help us do that,” Sitake said in a statement. “Nu‘u gets the most out of his athletes and I know he will help our team be tough and prepared. I’m excited to have him leading our strength and conditioning program.”

Sitake now has six assistants on his staff, along with offensive coordinator Ty Detmer, defensive coordinator Ilaisa Tuiaki and assistant head coach Ed Lamb.

Kaufusi, who has been coaching at BYU since 2002, is the only holdover from coach Bronco Mendenhall’s staff.

Empey, a former BYU offensive lineman, has coached at BYU and UNLV and is the former head coach at Snow College.

“I’m excited for this opportunity to come back to BYU and grateful to work with coach Sitake and Ty,” Empey said.

Tafisi, an East High product, previously worked at USC, Utah, Boise State and Cal in those programs’ strength and conditioning programs. He was the assistant strength and conditioning coach with the Trojans last season.

“It's a dream come true to be here at BYU,” Tafisi said. “I love working with these young players and being with them in the weight room to get them ready for game day.”
