Anthony Castonzo: C+
Castonzo did a decent job for most of the game, but had some troubles with Justin Houston and some communication issues with both Donald Thomas and running backs that allowed for pressure on Luck.
Donald Thomas: B-
Thomas run blocked well, and kept Luck clean for the most part. He did allow a few linemen to get around him to the outside a few times, and he didn't always pull well enough to be effective on guard-pulling plays.
Samson Satele: C-
Satele was asked to double-team players more often than not, but still allowed pressure on too many plays, including Luck's second touchdown pass. Satele has to be able to consistently maul people in the run game if he's not going to pass block well, and I don't see that happening.
Mike McGlynn: D+
Easily the Colts' weakest link, Indianapolis tried to hide McGlynn as much as possible, but he still got pushed back into Luck's face too often and couldn't pave the way in the running game.
Gosder Cherilus: C
Cherilus was a decent pass protector in this one, not having any huge gaffes but allowing a few pressures around the edge, and wasn't effective in the run game.
