Former Buffalo Bills and Jacksonville Jaguars head coach Doug Marrone has joined Boston College as the Eagles' senior analyst for football strategy/research, per ESPN's Pete Thamel.

Marrone will work under new BC head coach Bill O'Brien, who was most recently the New England Patriots offensive coordinator.

Those two worked together on the Georgia Tech staff from 1996-1998 and again in 2021 at Alabama, where O'Brien was the offensive coordinator/quarterbacks coach and Marrone coached the offensive line.

Marrone, 59, led the Bills in 2013 and 2014 after parlaying a successful 2012 campaign as Syracuse's head coach (8-5 record, Pinstripe Bowl win) into an NFL gig.

The Bills went 6-10 in 2013 but improved to 9-7 in 2014. However, Marrone triggered an "out" clause in his contract, which was activated after an ownership change to Terry and Kim Pegula in October 2014.

Marrone landed with the Jacksonville Jaguars as assistant head coach and offensive line coach in 2015. Near the end of the 2016 season, he took over as interim head coach following the firing of Gus Bradley.

Marrone then became the full-time head coach in 2017 and proceeded to lead Jacksonville as close to the Super Bowl as it's ever been. The 2017 Jags, which had a dominant defense nicknamed "Sacksonville," led 20-10 in the AFC Championship Game at the New England Patriots before the Pats came back to win.

It all fell apart in Jacksonville from that moment forward, with the team going 12-36 over his next three seasons, including a 1-15 mark in 2020.

Jacksonville parted ways with Marrone after that season, and he landed with Alabama for a year before becoming the New Orleans Saints offensive line coach in 2022 and 2023. The Saints then parted with Marrone after the season.

Now Marrone is back in college, where he coached from 1992-2001 as an assistant at six different stops before heading to Syracuse as its head coach from 2009-2012.
