A look at the Colts' Week 4 opponent: Jacksonville Jaguars

INDIANAPOLIS -- The Indianapolis Colts are supposed to have a lot of success this season based off their schedule.

On paper, that is.

Yes, they play in the AFC South, one of the worst, if not the worst, divisions in the NFL. They also play the NFC South, which had a team with a losing record -- the Carolina Panthers -- make the playoffs last season, and the AFC East, which only had the New England Patriots make the playoffs last season.

But each season brings changes to rosters.

We're going to take a look at the Colts' week-by-week opponent for the 2015 season. Today we take a look at the Jacksonville Jaguars.

2014 record: 3-13

First-round draft pick: DE Dante Fowler Jr.

Veteran additions: WR Bryan Walters, OLB Dan Skuta, CB Davon House, DT Jared Odrick, OG Jermey Parnell, TE Julius Thomas, S Sergio Brown, C Stefen Wisniewski, RB Bernard Pierce

Veteran subtractions: ILB A.J. Edds, CB Alan Ball, WR Cecil Shorts, TE Fendi Onobun, OLB Geno Hayes, OLB J.T. Thomas, OG Jacques McClendon, RB Jordan Todman, DE Red Bryant, S Sherrod Martin, CB Teddy Williams, CB Will Blackmon, TE Marcel Jensen, WR Tommy Streeter

Area of concern for the Colts: The Jaguars went out and got second-year quarterback Blake Bortles some help when they signed former Denver Broncos tight end Julius Thomas. Thomas had 13 catches for 157 yards and three touchdowns against the Colts last season. Of course, Thomas no longer has Peyton Manning throwing him the football. Jacksonville selected running back T.J. Yeldon and receiver Rashad Greene in the draft to give Bortles some additional skill position players. The addition of Stefen Wisniewski gives the Jaguars a veteran center.

Area that favors the Colts: The Jaguars suffered a substantial blow when Dante Fowler, the No. 3 overall pick, suffered a torn ACL during offseason workouts, ending his season. Bortles threw 17 interceptions in 14 games last season. Three of those picks came against the Colts.
