Hoke has a long history in the NFL and college football as a defensive backs coach, most notably with the Houston Texans between 2002 and 2008 and with the Chicago Bears, where he coached defensive backs from 2009 to 2014, which included a couple of dominant years under Lovie Smith before the defense immediately fell apart once he left. Last year, Hoke was the defensive backs coach and co-defensive coordinator for the South Carolina Gamecocks, responsible for the pass defense. While in Chicago, he worked with current Buccaneer Major Wright as well as free agent-to-be Chris Conte.
By hiring Hoke, the Bucs have completed the core of their defensive coaching staff in less than a day. Mike Smith's appointment as defensive coordinator was announced during Dirk Koetter's first press conference as head coach yesterday, and Alex Marvez reported the hiring of linebackers coach Mark Duffner and defensive line coach Jay Hayes not long after. They'll likely add a few assistants for these position coaches, but the main group of coaches should be in place.
Meanwhile, Koetter has yet to make any changes to his offensive coaching staff despite announcing yesterday that some would be coming. Most notably, he hasn't named an offensive coordinator. We should expect that to happen over the next couple of days.
