INDIANAPOLIS – In the trenches is where the questions lie for the Colts offense this season.
Over the next week and a half, Colts.com will take a look at the "Burning Questions" surrounding all position groups entering 2015.
Here's a look at the offensive line burning questions heading into the offseason program:
What are the scenarios regarding right tackle Gosder Cherilus?
Of all the "injury watches" at Training Camp this year, the Gosder Cherilus watch is the most significant.
The reason being, if Cherilus can't return to form, the Colts will have a domino effect on their offensive line.
If Cherilus isn't able to go, second-year lineman Jack Mewhort seems to be the guy called upon to move over from left guard. Mewhort played one game at right tackle in 2014, but logged reps there throughout the Colts offseason program this past spring.
Cherilus' absence would obviously open up a spot at left guard.
Lance Louis and Hugh Thornton have seen reps there (a healthy Donald Thomas would seem to factor into this situation, too).
Tackle depth behind Mewhort includes Joe Reitz, who has proven himself to be more than capable of playing several line spots in a pinch.
The Colts have had the whole offseason program to prepare for life without Cherilus.
Was that just preparing for the worst? Or will his absence become a reality in August and September?
If Cherilus can return to the lineup, that would do wonders for the Colts quality of depth along the offensive line.
STAT TO NOTE: Anthony Castonzo's 1,155 offensive snaps played last season were the most of any offensive lineman in the NFL.**
Is new offensive lineman Todd Herremans the starting right guard in 2015?**
As the Colts made their way through the offseason program, it became more and more clear that Todd Herremans is the favorite at the right guard position.
Herremans, who came over to Indianapolis after 10 seasons in Philadelphia, has 23 career starts at right guard.
The entire guard depth is going to be a storyline in itself during Training Camp.
You have starting experience from Herremans, Lance Louis, Hugh Thornton, Jack Mewhort and Joe Reitz, with some of those guys having the flexibility to slide outside, too.
Former Eagles head coach Andy Reid calls Herremans "dirty tough" and the Colts would obviously welcome such tenacity to their offensive line.
Herremans was the lone free agent addition the Colts made on the offensive line in 2015.
STAT TO NOTE: In his 10 NFL seasons, Todd Herremans has started at least six games at four different spots on the offensive line (6-LT, 71-LG, 23-RG and 24-RT).**
Who will win the center competition at Training Camp?**
From a pure one-on-one position battle, center will probably be the closest race this offseason.
Khaled Holmes and Jonotthan Harrison, the two centers to start the final four months of the season, are the two vying to snap the ball to Andrew Luck in 2015.
Holmes closed out the 2014 campaign as the starting center and was the starter when the Colts ended mini-camp back in June.
The former fourth-round pick in 2013 was the likely starter at center last year before a high ankle sprain in the preseason opener thrust Harrison (and eventually A.Q. Shipley) into a starting role.
Chuck Pagano said at the end of mini-camp that he would like to get an early starting five up front at Training Camp, and allow that starting group to mesh together.
Does that mean the center rotation won't be much of a revolving door once camp starts?
Holmes appears to be the favorite to be the starting center in 2015.
STAT TO NOTE: Entering Training Camp, the Colts have 10 offensive linemen who have started games in the NFL.
2015 Offensive Linemen (17): OG-David Arkin (4th Year), OT-Anthony Castonzo (5th Year), OT-Gosder Cherilus (8th Year), OG-Will Corbin (Rookie), OT-Denzelle Good (Rookie), C-Jonotthan Harrison (2nd Year), OG-Ben Heenan (Rookie), OG-Todd Herremans (11th Year), C/OG-Khaled Holmes (3rd Year), OT-Tyler Hoover (1st Year), OT-Ulrick John (2nd Year), OG-Lance Louis (6th Year), OT/OG-Jack Mewhort (2nd Year), OG-Joe Reitz (5th Year), OG-Donald Thomas (8th Year), OG-Hugh Thornton (3rd Year), C-Brandon Vitabile (Rookie).Roster Outlook*: Last year, the Colts kept 10 offensive linemen on their 53-man roster after the preseason. With all the injuries in 2015, that number stayed about the same throughout the regular season. The Colts are inevitably going to have to make some difficult roster moves up front in 2015. There are 10 players with starting experience on the line. Then you have young guys in Ben Heenan, Denzelle Good and Ulrick John all with practice squad * eligibility. The Donald Thomas' injury watch is going to be another key at camp. If healthy, Thomas could be a major X-factor.
