I have a great feeling about this week. Indy has the WORST (ranked 32nd) run defense in the league. Portis is a monster against any defense, but will slaughter the Colts.
I looked up Brunell and Manning's stats for the last 3 games they played (to be fair since it took a few weeks for Saunders' offense to begin clicking, this also tossed out the games against the Texans for both teams) and Brunell has had a few more passing yards than Manning and has only one less TD pass.

The old man can still play and after Portis scares the crap out of Indy's D, our WRs and Cooley will be able to get open.
The Titans held the Colts to 7 points for most of the game and they finished giving up 14. The next week, we scored 22 against the same defense. We CAN outscore the Colts, especially with out running game. I expect CP and Betts to have big days. When we can run 30+ times in a game, we're nearly unbeatable.
Our defense is the key. Last week, we were without Joe Salave'a and Corn Griffin. Rogers broke a bone too and Springs was just back.
This week at CB, we'll start Springs and possibly Troy Vincent, who is well-rested, healthy and already knows Williams' defense pretty well. He was a great signing, especially how desperate we are at CB.
Oh, and John Hall is sitting where he belongs.
I think we'll be the first team to beat a Colts team who is VERY lucky to be undefeated. They've been shaky and lucky this year.
