For the Indianapolis Colts’ offensive line, three of five positions are already locked in.

Anthony Castonzo is their left tackle and has been since 2011, Jack Mewhort is their left guard as long as he’s healthy, and Ryan Kelly is their incredibly promising second-year center. Those three provide quite a bit of stability up front for a unit that has struggled over the last several years. The other two spots, however, are much more up for grabs.

While there will be competition for the right guard and right tackle spots, it seems that there are clear frontrunners for those spots right now as OTAs come to a close. So far, it has been Joe Haeg at right guard and Le’Raven Clark at right tackle. Colts.com’s Kevin Bowen wrote today that “so far this offseason, a definite starting offensive line has been witnessed,” and later added that, “[Chuck] Pagano says some shuffling will occur on the line this offseason, but we have not seen too much of it yet.”

It should be noted that the media is only at one practice a week during OTAs, so in the grand scheme of things it’s a small sample size - meaning that it could just be coincidence (or intentional) that the shuffling occurs on days where practice is closed. We can’t rule that out, but it seems that most often that isn’t the case in OTAs and that the media does get a decent look at what the Colts are thinking right now.

So while there will certainly be competition, it seems that those two spots are Haeg’s and Clark’s to lose. And in all honesty, that shouldn’t be surprising either, since those two guys wound up finishing the season as the starters at those respective positions. The final few weeks of the season was the best that the Colts’ offensive line played last year, and it featured three rookies. Both Haeg and Clark showed off some of their potential, and so it makes sense that the Colts would give them the first shot at winning those jobs.

There will be competition from others, however, like Brian Schwenke and Denzelle Good. I would expect them to get some significant opportunities to showcase their abilities in training camp and preseason, so this always could change. But right now, Joe Haeg and Le’Raven Clark seem to be the clear frontrunners along the right side of the offensive line as the Colts wrap up OTAs and head into their mini-camp next week.
