AFC South: Lance Louis

Examining the Indianapolis Colts' roster:

QUARTERBACKS (2)
This is the safest position on the roster for the Colts. They plan to always keep a veteran backup if Luck ever goes down with an injury.

RUNNING BACKS (4)

The Colts will have a solid running combination if -- and we’re saying if until proven wrong -- Richardson can bounce back from a poor first season in Indianapolis and Bradshaw and Ballard can stay injury-free. Havili, a fullback, gets the edge over Mario Harvey, who switched from linebacker to fullback during offseason workouts.

RECEIVERS (5)

The final receiver spot will come down to Rogers and Griff Whalen. If the Colts want to play it safe, Whalen is the guy because he’s familiar with Luck and offensive coordinator Pep Hamilton, but Rogers has the size and speed the team likes. There’s also the possibility of the Colts keeping six receivers.

TIGHT ENDS (4)

Allen, who missed all but one game in 2013, and Fleener have the potential to be one of the top tight end duos in the league. Doyle and Saunders are both familiar with the system after backing up Fleener in Allen’s absence last season.

OFFENSIVE LINEMEN (9)

There are plenty of questions surrounding the offensive line outside of tackles Castonzo and Cherilus. The one thing general manager Ryan Grigson wanted with this group is depth. The Colts have plenty of it.

DEFENSIVE LINEMEN (6)

Like the offensive line, the Colts want depth on the defensive line so they can constantly rotate in players, so come the fourth quarter they still have fresh legs to get after the opponent. Jones was the key offseason acquisition for the Colts. Chapman showed flashes last season; now he needs to do it every snap that he’s on the field.

LINEBACKERS (10)

All eyes will be on outside linebacker as the Colts look to find a replacement for Mathis, who is suspended for the first four games of the season. Werner gets the first crack at starting in Mathis’ spot. McNary is a player for whom Grigson has high expectations. It’ll be up to defensive coordinator Greg Manusky on how he uses McNary.

DEFENSIVE BACKS (10)

It’s anybody’s guess how the secondary will perform. It’s anybody’s guess who will start alongside Landry at safety. It looked like it would be Howell for most of the offseason, but the Colts signed the veteran Adams in June. Can Toler finally remain healthy? Can Davis live up to his contract? So many questions with no answers at the moment.

SPECIALIST

This only changes if an injury occurs.
Here's Part I of the Colts Mailbag. Part II will run Sunday Mike Wells: Delano Howell appeared to be the frontrunner -- and he still may be -- the entire offseason until the Colts signed Adams to take Corey Lynch's spot on the roster. The Colts could have easily gone out and signed a young player, but they didn't. They signed a proven veteran, one who was on the roster of a team -- Denver -- that played in the Super Bowl last season. Howell lacks starting experience. The Colts aren't handing the starting spot to Mike Adams, but don't be surprised if he ends up starting alongside LaRon Landry at safety. Wells: Second-round pick Jack Mewhort. The offensive lineman is capable of playing all five positions on the line. A positive for Mewhort is that he moved ahead of Lance Louis and was working with the first unit by the end of offseason workouts. The competition for that starting spot will intensify in training camp once Donald Thomas starts practicing. It'll be Louis and Thomas as the two primary players pushing Mewhort for that starting spot. Wells: The Colts have about $13.7 million in salary cap space left. Colts GM Ryan Grigson said a number of times earlier in the offseason that they didn't plan to use all their salary-cap space because they'll have to pay players like Andrew Luck and T.Y. Hilton at some point down road. Wells: That's strictly up to Daniel Adongo. Practice well and play well in the preseason and he'll have a chance to get on the field in a game. The opportunity will definitely be there early in the season when linebacker Robert Mathis is serving his four-game suspension. Playing time at Mathis' position is far from set. It's up to Adongo to prove he deserves to get snaps. Wells: It's way, way too early to tell if Ahmad Bradshaw can stay healthy. Teams don't wear pads during offseason workouts, and even then, Bradshaw joined the quarterbacks and fellow running back Trent Richardson by wearing a red non-contact jersey. Bradshaw's health was the only thing that stopped him from being the Colts' starting running back last season. Bradshaw and Richardson were the only two running backs of three expected to push for the starting spot to take part in offseason workouts. Vick Ballard, the third, is still working his way back from a torn ACL.
INDIANAPOLIS -- The final significant days of the offseason for the Indianapolis Colts (outside of when commissioner Roger Goodell disciplines owner Jim Irsay) starts Tuesday at the team's facility when they begin the first of three days of mandatory minicamp before breaking up for the final time prior to reporting for training camp July 23.

Let's take a look at several things to pay attention to during the camp:

Brian Spurlock/USA TODAY SportsThe competition at running back, including Trent Richardson, won't be decided in this week's mandatory minicamp.
Offensive line battle: You can go ahead and put Khaled Holmes down as the starting center, but with Donald Thomas (quad, bicep) still working his way back, the starting guard positions could end up taking some time. Hugh Thornton, who took Thomas's spot after he was injured last season, has been working with the first team at right guard during organized team activities. Lance Louis had been working with the first team at left guard, but rookie Jack Mewhort, the Colts' second-round pick, moved ahead of him last week. The competition will intensify during training camp.

Running back competition: Just like the battle for the starting guard position, we won't get full competition for the starting running back position because Vick Ballard (knee) isn't expected to take part, as he's still working his way back from ACL surgery. Trent Richardson and Ahmad Bradshaw, the other two primary candidates, both wore red non-contact jerseys during OTAs. So this is another competition that won't pick up until training camp. All three players will get playing time, but keep in mind that coach Chuck Pagano said earlier in the offseason they want a workhorse in the backfield.

Landry sighting: Safety LaRon Landry has been the most significant healthy player missing during OTAs. It's not required for players to attend OTAs and Landry prefers to work out on his own during the offseason. But it still would have been good if he would have popped in for some of the workouts because of the need for improvement for the defense, the transition from a seasoned veteran in Antoine Bethea to possibly Delano Howell, who lacks significant experience, and Landry simply didn't have a great first season with the Colts. The offense, as long as Andrew Luck is the quarterback, will be fine. He's shown he can be effective even without good blocking. The same can't be said about a defense that finished 20th in the league last season.

The Bjoern factor: The fact linebacker Robert Mathis (suspension) won't be with the Colts the first four games of the season has definitely sunk in. Now it's up to second-year player Bjoern Werner, who gets the first shot to start in Mathis's absence, to prove he was worth the Colts selecting him in the first round after an inconsistent rookie season. "This year it's just knowing the defense and to feel comfortable in the defense," Colts defensive coordinator Greg Manusky said. "Now it's just his ability to get to the passer, which it's kind of you want him to do that in these OTAs, but he's never really going to get there because you don't have the pads on. But he's been doing a great job at least from the calls and signals and getting everything lined up and knowing exactly what he's supposed to do. It's a great situation for him."

Can Adams help: The Colts signed veteran safety Mike Adams over the weekend to take Corey Lynch's spot on the roster after placing him on injured reserve. Howell is leading the race to start, but Adams has started 73 games in his career. The question about Adams is: Does he have enough left in his 33-year-old body to help the Colts and possibly supplant Howell as the starting safety alongside Landry?

Who won't be there: Barring a sudden change of events, here are the players -- not including those on injured reserve -- you won't see taking part in minicamp. Receiver Reggie Wayne (knee), Ballard (knee) and Thomas (quad, bicep).
