It's that time. Over the next four weeks, the Times-Union will work to predict what the Jacksonville Jaguars will do to improve their team in this month's NFL Draft with mock drafts coming every Monday in the lead-up to the event that begins on Thursday, April 25. The Jaguars have spent the last couple of months working to re-structure their team with new player additions and the addition of defensive coordinator Ryan Nielsen and his staff. Jacksonville moved on from a trio of defensive veterans including safety Rayshawn Jenkins (Seattle Seahawks), defensive lineman Foley Fatukasi (Houston Texans) and cornerback Darious Williams (Los Angeles Rams). They also lost starting receiver Calvin Ridley to the division-rival Tennessee Titans.
