Practice squad: NT Joey Mbu, WR Devon Wylie, QB Matt Simms, CB T.J. Heath, G Ben Garland, TE D.J. Tialavea, RB Gus Johnson
Starts in 2015: Worrilow (12), Schraeder (12), Therezie (2)
Highlights: DiMarco, undrafted out of South Carolina in 2011, is having a Pro Bowl-caliber season as a blocker while adding the first two touchdown receptions of his career. He has been steady all around and seemed extra motivated from the moment he was required to compete with the now-injured Mooney for the starting job. ... Although Worrilow has been the subject of criticism for some missed tackles and coverage hiccups, he remains on pace to lead the team in tackles for the third consecutive season.
