Under Arians, the Colts relied on a high-volume passing game that sought to pick up yards in chunks. Andrew Luck averaged a healthy 12.9 yards per completion. Luck is very unlikely to approach that number in 2013, and his attempts will likely also be down. "The short, efficient passing game, a high completion rate," Hamilton explained when quizzed on what he's aiming for. "I'm a big believer of the power-running game and I think that ultimately opens up your passing game, the play-action passes." The Colts were in the middle of the pack when it came to play-action in 2012, but that figures to rise under Hamilton. We might be a bit wary of expecting Luck to top 4,300 yards passing again.
