Tennessee football coach Jeremy Pruitt details staff hires, including Tyson Helton, Kevin Sherrer

Tennessee coach Jeremy Pruitt completed his staff over the weekend by making David Johnson of Memphis his wide receivers coach.

UT hasn't confirmed the hire, but Johnson changed his profile picture on Twitter to one of him wearing a Tennessee shirt, and Memphis coach Mike Norvell announced Sunday that Johnson left his staff to pursue another coaching opportunity.

Pruitt confirmed his other nine assistant coach hires at a news conference last Wednesday. Johnson fills the final slot. A new NCAA rule allows for 10 assistants. Previously, coaching staffs were capped at nine.

Here's a look at Pruitt's inaugural coaching staff.

Tyson Helton

Position: Offensive coordinator/quarterbacks coach

Previous position: Southern Cal quarterbacks coach/passing game coordinator

The skinny: Helton has spent the past two seasons on the staff of his brother, Clay, at USC, where he tutored Trojans quarterback Sam Darnold. Helton has offensive coordinator experience, serving in that role from 2014-15 at Western Kentucky under Jeff Brohm.

Kevin Sherrer

Position: Defensive coordinator/inside linebackers coach

Previous position: Georgia outside linebackers coach

The skinny: Sherrer had been the last holdover from Mark Richt's final staff at Georgia, where Sherrer coached for four seasons. Sherrer and Pruitt worked on staffs together at Hoover High School, Alabama and Georgia. Sherrer's lone season as a defensive coordinator came in 2013 at South Alabama.

Will Friend

Position: Offensive line coach

Previous position: Colorado State offensive coordinator/offensive line coach

The skinny: Friend was Pruitt's teammate for two seasons at Alabama. He's in his third season at CSU. The Rams rank 11th nationally in total offense, and they surrendered just 13 sacks, tied for the fifth fewest in the nation. Before joining Mike Bobo at CSU, Friend worked under him while Bobo was the offensive coordinator at Georgia. Friend was the Bulldogs' offensive line coach for four seasons.

Robert Gillespie

Position: Running backs coach

Previous position: Tennessee running backs coach

The skinny: Gillespie, regarded as a strong recruiter, is the only holdover from Butch Jones' final staff. Gillespie has spent the past five seasons at Tennessee. He added the title of recruiting coordinator in 2015.

David Johnson

Position: Wide receivers coach

Previous position: Memphis wide receivers coach

The skinny: Johnson coached Memphis' wide receivers for two seasons. The New Orleans native has strong ties to Louisiana. He previously coached at Tulane for four seasons, overseeing running backs and tight ends.

Before that, he coached St. Augustine High School in New Orleans for three seasons. He was considered a valuable recruiter at Memphis. This wasn't Johnson's first chance to coach in the SEC. He turned away an overture from LSU last year.

Brian Niedermeyer

Position: Tight ends coach

Previous position: Alabama assistant director of personnel operations

The skinny: Niedermeyer is coming with Pruitt from Tuscaloosa. Niedermeyer previously was wide receivers coach at East Texas Baptist, a Division III school, and was a defensive quality control coach for Miami. He becomes an on-field Division I assistant for the first time. He played tight end at Arkansas-Pine Bluff.

Terry Fair

Position: Cornerbacks coach

Previous position: Colorado State cornerbacks coach

The skinny: Fair was a two-time All-SEC cornerback at Tennessee before becoming a first-round draft pick. He was a graduate assistant at UT in 2013-14 before spending the last three seasons at Colorado State. The Rams ranked ninth nationally in passing defense in Fair's first season before dropping to 32nd last year and 96th this year.

Charles Kelly

Position: Safeties coach/special teams coordinator

Previous position: Florida State defensive coordinator

The skinny: Kelly and Pruitt worked together in 2013, when Pruitt was FSU's defensive coordinator and Kelly was the Seminoles' special teams coordinator.

Before going to FSU, Kelly worked seven years as an assistant for Georgia Tech.

Chris Rumph

Position: Co-defensive coordinator/outside linebackers

Previous position: Florida defensive line coach
