While the position Williams will coach at UNC has not yet been confirmed, he has spent his last 13 seasons, in college and the NFL, as a wide receivers coach.
An Arizona official contacted by Inside Carolina Friday afternoon said Arizona head coach Mike Stoops has confirmed that Williams is leaving to take a job on the UNC staff.
Williams was the wide receiver coach at Miami for three seasons (1993-95), one of which was under Davis. He then coached in the NFL for six seasons (1996-2001) as the receivers coach for the Tampa Bay Buccaneers. Williams returned to the college ranks in 2003 to coach wide receivers at South Carolina, and then joined Mike Stoops' staff at Arizona the following season at the same position and has been there since.
Williams has heavy West Coast ties, as he is a native of Long Beach, Calif. and began his coaching career at Long Beach City College in 1984. That was followed by stints at New Mexico State (1986-87), Texas Christian (1988-91) and Minnesota (1992), before joining the staff at Miami in 1993.
Williams played defensive back at Colorado State and graduated in 1982.
He is the second assistant to be added to the staff since the hiring of Davis. Steve Hagen was officially announced as an offensive assistant on Friday (link). Three assistant coaches from last year's staff -- offensive coordinator Frank Cignetti, assistant head coach John Gutekunst and offensive line coach Mark Weber -- have been released thus far.
