Drew Stanton knows Bruce Arians’ system quite well from working as Andrew Luck’s backup, and could have a chance for some playing time in Arizona.

His departure to the Cardinals means the Indianapolis Colts have a new need: A No. 2 behind Luck. It's hard to envision Chandler Harnish, the last pick of last year's draft, seizing the job. He'll be learning a second offense in his second year.

The list of free-agent quarterbacks is a poor one.

Ryan Fitzpatrick was just cut in Buffalo. Jason Campbell could be a functional spot starter.

The Colts might need to pounce on one of them given the other options: Josh Johnson, Charlie Batch, Rex Grossman, Kellen Clemens, Byron Leftwich, Tyler Thigpen, David Carr, Josh McCown, Brady Quinn, Luke McCown, Caleb Hanie, Matt Leinart or Jordan Palmer.

I’m thinking the same thing you’re thinking: I sure hope Gosder Cherilus and Donald Thomas upgrade Luck’s protection, because the Colts can’t afford for him to be hurt.
