I posted this as a response the writer of an article on Bleacher Report that asserts the Steelers will win between "3-5 games this year." I called him out on why I thought that was wrong, and when he questioned me further, I wrote this in response. I thought it served a purpose here as a template for you all to correct me or agree with me on the reason we will succeed or fail this year.
This is the article by the way: http://bleacherreport.com/articles/385135-afc-north-premature-predictions
The team brought back Randle El who fits the system, Mike Wallace will be improved upon an amazing rookie year. They added depth to the best LB corps in the NFL and the only "weakness" in the group, they add strength behind him with a veteran and former starter in the system (who I might add had a great year in Det) Larry Foote. You assert that Colon is the only serviceable OL that they have, but you forget that Chris Kemeoatu is one of the best pull-guards in the NFL and missed most of last year, and the line will be strengthened with Pouncey at G. You think that Pouncey is overrated, and you are allowed to have your opinion, but the record shows that the Steelers under Colbert don't miss on 1st rounders: so I will let history speak for me. With the loss of Holmes, that is hard, but with Wallace stepping into a starting role he was ready to fill, Randle El in the Slot and now Sanders primed to be the 4 (heck, maybe Sweed holds onto a ball) and you have a pretty darn good receivers group. The main flaw in the offense last year was they couldnt move the chains close. Dwyer is the type of back who hammers away at the will of LB's and DL-men. Add Dwyer to an ever-improving Mendenhall, and voila, you have a pretty darn good running game. Heath Miller is coming off his best season as a pro and second year man David Johnson proved at the end of the season to be the best blocking TE the Steelers have had since Mark Bruener. Having Troy back for an entire season, a healthy D-line that saw two starters miss significant portions of the season, and having Bryant McFadden back moving William Gay back to his more natural position of Nickel will help (since McFadden doesn't fall every other play). Plus, Carter is no longer on the Steelers, Ryan Clark is the starting safety opposite Troy, so that makes us a better team, and Clark's backup is Will Allen, a more talented back-up than Tyrone Carter at this point in their careers.
