After interviewing the internal candidates on Tuesday, the Detroit Lions are meeting with their first external option for the team’s head coaching vacancy Wednesday, hosting Houston Texans defensive coordinator Mike Vrabel. And even though it’s been a decade since they’ve worked together, Lions general manager Bob Quinn knows Vrabel well. While Quinn served in various scouting roles for the New England Patriots from 2001-08, Vrabel was playing a key role on defense, special teams and as a situational tight end for the franchise that won three Super Bowls during the stretch. Given this is Quinn’s first time going through a coaching search, he acknowledges that familiarity could give a candidate an advantage. “It could factor in, for sure, it could,” Quinn said. “But that’s why the interview process is what it is. You spend time with people you may not know, and you get to know them, and maybe they change your opinion on them one way or the other. But it’s a factor.” A quick glance at Vrabel’s coaching resume isn’t going to wow anyone. Since wrapping up his 14-year playing career, he’s been coaching seven seasons. The transition surprised no one, especially former coach Bill Belichick.
