For the most part, free agent signings that take place for the next several weeks won't have a tremendous impact on the 2013 exploits of the teams involved (with notable exceptions such as the team that eventually lands Brian Urlacher or Charles Woodson). But, sometimes we learn extra information based upon what transpires, and such is the case with veteran OT Guy Whimper signing with the Steelers on Monday.
