This is actually a blessing in disguise for Pittsburgh. The youth movement has arrived and the speed replacing Ward is incredible. I love Hines, a true Steeler but he has become a liability with the speed going on around him this season. Emmanuel Sanders replaces Ward and Jericho Cotchery (who's mean around the goalline and plays a lot like Hines, not to mention facing N.E's D all those years with the Jets) will also get extensive playing time.
As for Farrior? Another blessing. In all of those matchups against the Pats all those years, Farrior was the slowest and oldest in coverage. He will be replaced by Slyvestor Stevenson, who can hit, hard. Plus, Ziggy Hood, Cameron Heyward, & McClendon have been beasts on the d-line. Lots of youth. This will be a different Steelers team in recent years.
It will be either a Pats crushing or a Steelers surprise. Regardless, I expect to see both teams face each other again soon. Good luck. May there not be any more injuries, haha.
