The Dallas report cited three Cedar Hill players and said SicEm365.com first reported the news.
Baylor later confirmed the hiring in a news release.
“All I saw was that he was in tears,” wide receiver Camron Buckley said.
McGuire spent 14 seasons at Cedar Hill and won state titles in 2006 and back-to-back in 2013 and ’14.
He had an offer to join the Texas coaching staff as tight ends and special teams coach in 2015 but wanted his son Garret to finish high school at Cedar Hill before making a move.
McGuire is the third high school coach in Texas on Rhule’s staff. David Wetzel (Reagan; San Antonio) and Shawn Bell (Cedar Ridge) also are said to be joining the staff. Wetzel was the current president of the Texas High School Coaches Association. Bell is a former Baylor quarterback.
The specific positions for McGuire, Wetzel and Bell have not been announced.
Legendary Baylor football coach Grant Teaff had implored Rhule to go and hire some Texas high school coaches to build a bond to the state’s high school programs. He seems to have taken the advice to heart in a big way.
