Arizona State offensive coordinator and associate head coach Billy Napier

Arizona State offensive coordinator and associate head coach Billy Napier has been offered the head coaching job at Louisiana-Lafayette, according to a source familiar with the development.

Napier, 38, was just given a two-year contract and promotion by the Sun Devils after Herm Edwards took the program's head coaching job earlier this month.

ASU Athletic Director Ray Anderson spoke glowingly of Napier at a press conference that announced ASU's decision to fire previous head coach Todd Graham and move in a new direction with the program. Napier's retention was said to be an important part of the Sun Devils' football plans moving forward.

Footballscoop.com reported on Thursday that Napier was one of four men who interviewed for the position along with Penn State defensive coordinator Brent Pry, Nicholls head coach Tim Rebowe and Grambling head coach Broderick Fobbs.

Louisiana-Lafayette recently fired head coach Mark Hudspeth after seven seasons at the school. He had a 28-38 record including 5-7 overall and 4-4 in the Sun Belt Conference in 2017.

Hudspeth was reportedly making $1,150,000 annually at the time of his dismissal. Louisiana-Lafayette has extended a five-year offer to Napier, per a source.

Napier reportedly made $550,000 in his first year with the Sun Devils, 12th highest among Pac-12 assistant coaches at public universities that disclose such information.

In his first year with the the Sun Devils, Napier's offense finished sixth in the Pac-12 in yards-per-game, (427.6) tied for eighth in yards-per-play (5.6), and seventh in points per game (31.9). ASU led the Pac-12 in red zone efficiency and finished third in ball security and third in time of possession in 2017.

ASU's offense showed significant overall improvement from early in the season to how it performed after the bye week, when the Sun Devils went 5-2 to end the year.

The Sun Devils had the 14th highest-graded offense in the FBS this season according to Pro Football Focus, and the 10th highest-graded passing attack in the nation, dramatic improvements in execution from a year earlier when it was 54th and 86th in the same categories, respectively.

Napier and the rest of the team's on-field offensive staff from 2017 -- wide receivers coach Rob Likens, offensive line coach Rob Sale and running backs coach John Simon -- were retained by Edwards, a move that was articulated as a stabilizer for the program through the transition to Edwards.

Napier arrived at ASU after coaching wide receivers at Alabama from 2013-17. Before that he had coaching stops at Colorado State and Clemson, where he was the youngest offensive coordinator in Power-5 football in 2009-10.
