Could Packers GM Ted Thompson shock the world and make a deal for Pro Bowl receiver Brandon Marshall? I highly doubt it judging by Thompson's love for draft picks and his disdain for signing other teams free agents to lucrative deals. However you can't rule anything out and adding the 25 year old Marshall would transform one of the best offenses in the league in 2009 into potentially one of the best of all time.
The Packers are loaded at receiver with Greg Jennings, Donald Driver, James Jones, and Jordy Nelson. The Packers group rivals any in the league and depending on who they add to fill the number 5 spot could be the best in the NFL bar none. Marshall has to be mentioned but far more likely is a player like Brett Swain who beat out Ruevell Martin in 2009 mostly due to his special teams play. Charles Dillion an arena league standout with special athleticism and the ability to return kicks is also a possibility already on the roster.
Other options through the draft rage form players like Dez Bryant or Demaryius Thomas who could be heir apparent to Donald Driver but would cost a first round pick to players like Dexter McCluster and Jacoby Ford who would be impact players in the return game but likely not turn into more than a dangerous number three receiver due to their diminutive size.
