Little has changed on the Indianapolis Colts. Normally, free agency robs the Colts' defense as young starters hit the open market, but not this year. Head coach Tony Dungy is a master of taking raw, young athletes and fitting them into his Cover 2 scheme.
What we learned from minicamp
The offensive line looks solid despite the loss of right guard Jake Scott, who left for the rival Tennessee Titans in free agency. Charlie Johnson beat out Dylan Gandy for Scott's position, leading to Gandy's release. Mike Pollak, the team's second-round choice, is another option. Pollak is an interesting prospect. He'll compete for playing time at right guard and could be the long-term replacement at center for Jeff Saturday, who's entering the final year of his contract. The team would like to re-sign Saturday, a Pro Bowler who is among the best centers in football.
Peyton Manning is developing a chemistry with his receiving options both young and old.
A year ago, the Colts were blindsided by the retirement of Tarik Glenn and had to rush second-rounder Tony Ugoh into the starting lineup. Ugoh enters his second season confident that he fits well in the Colts' offense. The Colts ask their left tackle to block the opponent's top defensive end man-on-man without any help. Thanks to Ugoh's rapid development last season, the Colts ran their offense and got more pass-catchers into routes.
Ryan Lilja is solid at left guard. The return of Dominic Rhodes as a backup to Joseph Addai makes the backfield that much stronger. The plan was for sixth-round choice Mike Hart to get Rhodes' old job of getting eight to 10 carries a game. Now the Colts go three-deep at halfback.
The Colts have to develop key backups for their passing offense. Behind Marvin Harrison, Reggie Wayne and Anthony Gonzalez at receiver, the Colts don't know what they have. That was a problem last year. Injuries to their top three receivers in the middle of the season forced them to use Aaron Moorehead more than they planned. Moorehead is gone. The Colts are trying to develop Roy Hall, Devin Aromashhodu and former Titan Courtney Roby as fourth and fifth receivers.
With Harrison's knee being a question mark, that role is important if the Colts want to maintain their three-receiver offense without Harrison.
They also have to find a replacement for Ben Utecht (now with the Bengals) at tight end. Utecht caught 31 passes as the No. 2 tight end, and the Colts like to use the two-tight end set a lot. They didn't bring back Bryan Fletcher, so those backup tight end hopes ride with Gijon Robinson and fourth-round choice Jacob Tamme. The Colts think they will be OK at that position.
The Colts have major question marks heading into training camp, but the prognosis is encouraging. Harrison isn't expected to do much in training camp as he rests his aging knees. Harrison missed most of last season because of a bursa sac problem under the left kneecap that caused swelling when he ran. By resting the knee, Harrison hopes the swelling stays down and he can play the whole season.
Defensive end Dwight Freeney is coming off a Lis Franc foot injury. He probably won't do much in training camp, but he's expected to be ready for the regular season. Safety Bob Sanders is coming off shoulder surgery, but he's ready to resume his leadership role on defense.
The Colts' front office was confident of Harrison's innocence in a shooting incident near a bar he owns in Philadelphia. Though Harrison was questioned by police and there have been reports his gun was involved in the shooting, little has come out of the Philadelphia Police Department in the past couple months. At the very least, he could be guilty of a misdemeanor if his gun was involved. That's a state law, and that could cause some minor problems for Harrison with the league office. Still, that the case has been so quiet possibly confirms the team's confidence that Harrison wasn't directly involved.
Training camp start: July 24
