Can the Defense Improve?
While the Colts would tell you differently, this defensive cast for Indianapolis isn't all that different from the one that allowed 87 points in two postseason games last year. Sure, they added Jones and Jackson to the front seven and drafted a few depth players, but they also lost Bethea on the back end, Fili Moala to injury and two key depth linebackers in free agency.
The Colts are relying on young talent to make leaps forward in 2014, including names like Bjoern Werner, Josh McNary, Josh Chapman, Montori Hughes and Delano Howell. But the team also needs veterans like Landry, Toler and Jackson to step up and be much better than they were in 2013.
With Robert Mathis, the Colts' only pass-rushing threat, suspended for the first four games of the season, the Colts coaches have their hands full going into the 2014 season, especially when it comes to replacing Mathis' production.
Who Will Step Up on the Offensive Line?
While they didn't make any high-profile moves on the offensive line this offseason, the Colts did make changes. Khaled Holmes should get the full-time starting job at center, for example, and the Colts brought in former Chicago Bears guard Lance Louis as well as drafting Jack Mewhort out of Ohio State in the second round.
With Thomas also returning from injury, the group is full of questions, but also a lot of potential.
If Hugh Thornton and Khaled Holmes make second-year leaps worth discussing, the line will improve. If Thomas is as good as assumed after injury, the line will improve. If Mewhort makes an immediate impact, the line will improve.
Yes, the line's improvements are contingent upon development (and health), but there is a real chance that that development actually happens.
Sorting out the Weapons
This final "problem" is a good problem to have, but one that Hamilton struggled with last season: Who should get on the field?
With a plethora of offensive weapons, the Colts are deeper at skill positions than they ever have been in the Luck era. At wide receiver, the Colts have three proven veterans followed by three legitimate developing talents in Moncrief, Da'Rick Rogers and LaVon Brazill. At tight end you have two highly drafted players who each have flexible skill sets.
Plus, there's Hamilton's love for the power run game, heavy sets and fullbacks.
Last year, T.Y. Hilton was underused for the first half of the season, and now there are even more options to fill his spot on the field. Will we see Hamilton find a strong balance between his arsenal, or will his stubbornness on power running lead to unfortunate imbalances between skill players?
After seeing what happened last season, we can only hope that the second half of the season made a dramatic impact on the second-year coordinator.
