According to Pro Football Focus, the Indianapolis Colts had the second worst offensive line in football. When you take a gander at the amount of time Quarterback Andrew Luck spent on his backside, that shouldn't come as a surprise. Look, it's not a surprise that the Colts need to do some serious work on their offensive line this offseason. They were dismal this past year, and the Colts still made the playoffs at 11-5. Imagine how much more efficient the Colts could be, and more so, how much more efficient Andrew Luck would be, if he spent more time in the pocket than scrambling around outside of it. The only guys I am 100% okay with returning next year are Anthony Castanzo and Joe Reitz. Winston Justice wasn't horrible, however he was inconsistent and oft-injured. With him becoming an unrestricted free agent, I'm almost positive the Colts are going to let him go and find an upgrade through that same free agent class. Samson Steele also spent much of 2012 sidelined by injuries, and I don't think the Colts will resign Jeff Linkenback, who is set to become a free agent. AQ Shipley, Mike McGlynn and Bradley Sowell will be given the chance to make the team in camp. I could see Shipley making it, however, the other two really didn't distinguish themselves enough this past season. We're finished with defense and have moved to the big boys up front.
