Is this the year Jacksonville finally catches the Colts? The Jaguars are coming off an 11-5 season, and they have been very aggressive in trying to match up better against the Colts, who have dominated them in AFC South play.

Fantasy Update
AJ Mass breaks down the fantasy prospects for the Jaguars. Story

To help stop Colts quarterback Peyton Manning, Jags coach Jack Del Rio added Drayton Florence at cornerback and pass-rushers Derrick Harvey and Quentin Groves. The Jaguars also added WRs Jerry Porter and Troy Williamson to provide more explosiveness to the offense. With David Garrard established as the team's starting quarterback, the Jaguars feel good about their chances.

What we learned from minicamp

The roles of the wide receivers were established. Reggie Williams, coming off his best season with 10 touchdown receptions, will start at flanker. Porter will work as the split end, but Williamson will also get some time there. Williamson's deep speed was impressive, which was expected. What made Del Rio feel even better about the trade with the Vikings was how well Williamson caught the ball. Dennis Northcutt, who caught 44 passes for 601 yards last season, will work from the slot.

The odd man out appears to be former first-round choice Matt Jones. Jones' poor work ethic has caught up to him. Despite his great speed and size, Jones' production continues to drop. He went from 41 catches for 643 yards in 2006 to 24 catches and 317 yards last year. John Broussard, a seventh-rounder, shows some promise and could beat out Jones as the fifth receiver.

The Jaguars also came out of minicamp feeling positive about tight end Marcedes Lewis, even though he's battled knee problems this offseason. The 2006 first-round pick looks as though he's ready to have a breakthrough year. He caught 37 passes for 391 yards and two touchdowns last season. Garrard, who's emerging as a potential star at quarterback, will have plenty of weapons to move the offense.

Still unresolved

Lots of questions remain along the offensive line. Maurice Williams, Uche Nwaneri and Dennis Norman are in a three-way battle for the starting right guard spot, although Williams should be considered the favorite because he signed a four-year, $12.5 million extension. Left tackle is another question mark. Richard Collier is battling with last year's starter, Khalif Barnes, for the starting job.

All in all, the offensive line doesn't look as stable as it was a year ago. The team released guard Chris Naeole, who was perhaps the line's most consistent performer. Right tackle Tony Pashos remains a work in progress. Even though the team has more options than it did a year ago at this time, the blocking might not be as good. Still, there is plenty of competition, which could be a good thing.

Del Rio still has to sort out how he wants to handle his secondary, but that should be a pleasant challenge. His options are pretty good. He could move cornerback Brian Williams to safety, a position that surprisingly lacked playmaking ability in 2008. That would open up a starting spot for Florence at cornerback, where he would be paired with Rashean Mathis.

Injury analysis

The biggest concern is at tight end. Lewis is coming off knee surgery. George Wrighster might not be ready for camp because of knee surgery. Greg Estandia is coming off shoulder surgery but should be ready for camp.

Also, Porter has missed time this offseason with leg problems. There is some concern about the knee of WR Mike Walker. Mathis is coming off a torn quad from last year, but he was fine at the minicamp.

Time for a change

The Jaguars made bold decisions to improve their defensive line. They traded defensive tackle Marcus Stroud and replaced him with Rob Meier. For years, the Jaguars were known for their anchors at defensive tackle -- Stroud and John Henderson. Both players dared opponents to try to run on them, and they usually won those battles.

But the Jaguars learned that just stopping the run isn't good enough. They play in a division that features Manning, Vince Young and Matt Schaub. They have to get to the quarterback. The Jaguars changed their emphasis by bringing in Harvey and Groves to challenge Paul Spicer and Reggie Hayward for playing time as pass-rushers. They let Bobby McCray go to New Orleans in free agency even though he has had a 10-sack season.

Training camp start date: July 25
