The Indianapolis Colts open training camp on July 25 at Grand Park in Westfield, Indiana. Here's a closer look at the Colts camp:
Top storyline: Andrew Luck, of course. Barring a setback, the quarterback will participate in his first training camp in two years after missing the 2017 season while recovering from right shoulder surgery. Luck threw a football for the first time since October 2017 on the first two days of the team's minicamp last month. Some training camp days will be lighter than others for Luck as the Colts want to simulate the regular season as much as possible for him. The best news with Luck is that he said he will "absolutely" play in the team's Week 1 game against Cincinnati. A healthy -- and effective -- Luck will help cover up some of the Colts' flaws and potentially make them a better team than some expect.
QB depth chart: The Colts have experience at their top quarterback spots with Luck and Jacoby Brissett, who started 15 games last season after being acquired from New England a week before the regular season. Coach Frank Reich didn't rule out the possibility of the Colts keeping three quarterbacks next season. The tricky part about that, especially if Luck is healthy, is that it'll take up a roster spot of another position. If the Colts do keep three quarterbacks, the final spot will be between Phillip Walker and Brad Kaaya.
Bubble watch: Tight end Erik Swoope looked like he would be ready to slide into the No. 2 role behind Jack Doyle after he had 15 receptions for 297 yards during the 2016 season. But a knee injury cost him all of last season, and not participating in offseason workouts because of his continued rehab didn't help his cause. The Colts signed 2014 first-round pick Eric Ebron to be the No. 2 tight end and the team has been impressed with Darrell Daniels.
This rookie could start: There is no "could start" when it comes to Quenton Nelson, the No. 6 overall pick in the April draft. The Colts didn't use a high draft pick to have Nelson begin his NFL career as a backup. He spent the entire offseason working with the first unit at left guard. Poor offensive line play has played a significant role in Luck getting knocked around most of his career and missing 26 games over the past three seasons. Nelson will join an offensive line that features left tackle Anthony Castonzo, center Ryan Kelly, right guard Matt Slauson (who worked with the first unit in offseason workouts) and right tackle Denzelle Good, giving Luck possibly the best line of his seven-year career.
Three first-timers: The top three coaches -- Reich, offensive coordinator Nick Sirianni and defensive coordinator Matt Eberflus -- are all new to their roles. Reich is giving Eberflus most of the control of the defense, because Reich will be calling plays for the offense. Reich was able to learn how to juggle being the head coach and playcaller from Doug Pederson during the past two seasons with the Philadelphia Eagles.
Hurting at safety: The projected starters at safety -- Malik Hooker and Clayton Geathers -- spent the offseason workout period rehabbing and watching from the sidelines. Hooker is still working his way back from a torn ACL suffered in Week 9 last season, and Geathers, who has played a total of 14 games over the past two seasons, didn't participate in workouts because of an unspecified injury. Matthias Farley and T.J. Green are the two primary candidates to work with the first unit if Geathers and Hooker are still hurting at the start of training camp.
