Quite a few potential play-makers switched cities Thusday and these movements could have been just the first wave of things to come in a season where many teams are opting for change. The Arizona Cardinals decided against giving Anquan Boldin the large contract that he has been seeking since last season, instead agreeing to a trade that sends him to the Baltimore Ravens in exchange for a third- and fourth-round pick in the upcoming 2010 NFL draft. The Ravens’ receiving core gets the upgrade that it needed with Boldin, their lone 1000-yard receiver last year was 35 year old Derrick Mason. However it was definitely the the Chicago Bears that made the biggest moves, signing DE Julius Peppers, RB Chester Taylor and TE Brandon Manumaleuna. Peppers brings an immediate upgrade to a once dominant defense that has be lackluster that last couple of seasons. While blocking tight end Manumaleluna should help open holes for Matt Forte and the newly acquired Taylor. Meanwhile the Detroit Lions continue to rebuild with the signings of Nate Burleson and Kyle Vanden Bosch.
