The Pittsburgh Steelers made a lot of moves during the offseason last year, somewhat out of character for a generally conservative group when it comes to utilizing outside resources aside from the draft to enhance their team.
Despite the fact that they wound up adding two starters and two other players that logged starts for at least half the season due to injury, I believe most would still regard the acquisition of offensive line coach Mike Munchak as the biggest move that the organization was able to make between the 2013 and 2014 seasons.
