Would his signing make a huge differenceNot much

Not so comforting for Tomlin and company to think about.The front office is going to sign Tyler Palko, the former Pitt QB who was with Arizona during preseason, and make him the No 3. Palko won't be able to come in and pick up this offense in just six weeks. That's asking too much.The rumor mill is churning that the Steelers will try to sign Jeff Garcia for a worst-case scenario.Would his signing make a huge differenceNot much.Garcia is a capable veteran, but he is a product of the West Coast system. Favre struggled to learn a new offensive system, and New York faltered.Fast forward to 2009.Favre goes to Minnesota, where coach Brad Childress runs the same type of West Coast scheme Brett did in Green Bay for 16 years. The results: Favre is playing like he did at 30, and the Vikings are 9-1 atop the NFC North.Garcia has never played in the type of scheme Arians runs. Not good news with the amount of sacks this line gives up.The Steelers are riding a seesaw, teetering between prosperity and disaster.If they can tighten up the secondary minus Troy Polamalu, protect Roethlisberger better, improve the special team's play, and regain their focus and chemistry, success is assured.If they fail to shore up those weaknesses in the final six games, a long, cold winter awaits the Steeler Nation..

The Colts and Saints (ranked first and second last week) remain in the top two spots, as they should, while some unlikely upsets have shaken the rest of the rankings up a bit.Week 12 will start to open things up a bit with Indianapolis being tested by a hungry Houston team, while New Orleans will face quite arguably it's toughest test in the New England Patriots.Read on to see where your team ranks in Week 12's NFL Power Rankings: 1.

Indianapolis Colts (10-0) They aren't winning games by decisive margins at all, and this week's wasparticularly ugly, but winning iswinning, and undefeated is still undefeated 2. New Orleans Saints (10-0) They looked fantastic against a bad team, so that doesn't tell us a whole lot. They're still undefeated and easily among the elite in football, but they need to regain some consistency, and a good start would be by beating a worthy opponent in New England this week 3. Minnesota Vikings (9-1) They've been hearing from experts that their schedule has been soft, and that's why they are where they are.

Perhaps, but if they weren't as good as they look, they would have lost more games by now. New England Patriots (7-3) They destroyed the Jets and made RexRyan call them out for throwing the ball near the end of the game. They're in a nice spot, but the true test will be this week against the undefeated Saints on Monday Night Football 5. Arizona Cardinals (7-3) Kurt Warner's head injury probably isn't serious, so the Cardinals can sit back and relax with a 7-3 record. Even if they finished 9-7 again, this division is still likely theirs 7. Cincinnati Bengals (7-3) Just when they convince everyone that they're an elite team, they go and lose to the Raiders. They're right back where they were before they finished sweeping the Steelers 8.
