07:41 PM ET 12.08 | While the Titans, Colts and Jaguars each introduced top 10 quarterbacks into the AFC South in the 2011 and 2012 drafts, the Colts appear to have dramatically won that battle of new quarterbacks so far. Andrew Luck has set several NFL records in his rookie season, while Jake Locker has posted an unimpressive 2-5 record in his first seven games as a starter for the Titans. However, the Titans can deliver a big blow to the postseason hopes of the Colts with a win on Sunday. Indianapolis is on the verge of being eliminated in the race for the AFC South, but are leading the race for a wild card spot. With a pair of games against the Houston Texans still on the schedule, the Colts can't afford to drop a very winnable game against the reeling Titans that have lost four of its last five.
