Indianapolis' offensive line has a mission.
It must protect No. 1 draft pick Andrew Luck from oncoming pass rushers without self-destructing, and it won't be easy.
The Colts have changed their philosophy, bringing in lots of fresh faces and bigger bodies to help produce a stronger ground game. The hope is by bringing more balance to an offense that relied so heavily Peyton Manning's right arm, defenses will have to play more honestly, and that will give Luck a better chance to stay upright - and healthy.
The changes mean Indy will have at least three new starters for the Sept. 9 season opener at Chicago, and time is running short to get everybody working in unison. But the Colts insist it can be done.
