Highlights: There's no better undrafted free agent on the Colts than Vinatieri. The 42-year-old kicker has had a Hall of Fame career. He's made 495 out of the 590 field goals he's attempted in his career, including 17 of the 19 he's attempted this season, and he's showing no signs of slowing down. Adams is the backbone of the Colts' secondary after signing with the team in the middle of June 2014. He made his first Pro Bowl appearance last season and has a team-high five interceptions this season. Harrison is a favorite of general manager Ryan Grigson because of his size -- 6-foot-4 -- and blocking ability. Freeman led the Colts in tackles in his first two seasons in 2012 and 2013 and was second in that category last season.
