Not snarking, really want to know if you have some info I don't 

Has been successful wherever he's been.  Sounds like a guy who has been climbing the college football ladder for years.  I like that he has been OL coach, running game coordinator and offensive coordinator.

Brad Davis is in his first season as the offensive line coach with NT. Most recently, Davis was the offensive line coach at East Carolina.

In his one season at East Carolina, Davis helped guide the duo of running back Chris Hairston and quarterback James Summers to combine for 1,200 yards rushing and 16 touchdowns.

Prior to his one season at East Carolina, Davis played a key role in guiding prolific offenses at James Madison and Portland State. He was the JMU co-offensive coordinator and line coach during the 2014 campaign. He helped the Dukes to a 9-4 overall mark and the school's first Football Championship Subdivision (FCS) playoff appearance since 2011 after a third-place finish in the Colonial Athletic Association.

Davis and James Madison stood 10th nationally in total offense with a 484.6 yards-per-game average last fall, 17th in scoring with a 35.7 points-per-game clip and 21st in both rushing and passing. Behind the play of Associated Press Third-Team All-America quarterback Vad Lee, the Dukes established numerous school records, including passing completions, attempts, yards and touchdowns. In addition to Lee and receiver Daniel Brown, Davis also had a direct impact on the development of another All-CAA performer, offensive lineman Mitchell Kirsch.

Before joining JMU in 2014, Davis spent the previous five years at Portland State, serving as the run-game coordinator and offensive line coach as part of the program's pistol package. Under Davis, the Vikings had 10 players earn All-Big Sky Conference honors while ranking among the nation’s leaders in fewest sacks allowed.

In 2013, senior tackle Mitchell Van Dyk was named First-Team All-Big Sky as well as garnering third-team All-America honors by The Sports Network. The 2013 season was a record breaking one for PSU.  Davis helped lead Portland State to a Big Sky top team rank in total offense, second in rushing offense and third in scoring offense, while ranking third at the FCS level in rushing offense and total offense. The Vikings also set school records with 6,486 total yards, 3,330 rushing yards, a 277.7 rushing average, 540.5 total offense average and 36 ground touchdowns.

In his last two years at PSU, his line surrendered only a combined 19 sacks to rank ninth (2013) and fifth (2012) nationally, respectively.

Davis was an offensive line staff assistant at North Carolina in 2008 and also spent two years as a defensive line graduate assistant at Texas A&M, as well as a coaching stint at Doane (Neb.) College in 2005 and 2006.
