We’re back from the NFL’s scouting combine, and a little smarter and more informed for it. Detroit Lions head coach Dan Campbell and general manager Brad Holmes spoke from the podium in Indianapolis. And the team also hosted a small group of local reporters to talk with the team’s four top assistant coaches. Holmes has said defense is this team’s primary need. And defensive coordinator Aaron Glenn said they want to build this thing through cornerbacks and defensive linemen. That’s where MLive Lions beat writer Ben Raven’s head was at before the combine, and not much is changing after the week of brushing shoulders with the NFL world in Indy.
