The Indianapolis Colts have gotten a lot of mileage out of Andrew Luck's legs.
Maybe too much.
Shaky protection has forced Luck to scramble all over the field this season and it wasn't pretty again Sunday, with Indy down 20-7 to Tennessee at halftime after rushing for just 12 yards. By the time the game was over, rookie Vick Ballard had a season-high 94 yards rushing and the Colts had done enough to take some pressure off their star quarterback in a 27-23 win.
If only the Colts could run that way all the time. Indy's running game is better than it was last year, but it has been inconsistent. The Colts (9-4) are in position to make the playoffs, but it's unlikely they'll go far unless they improve their ground attack.
