Where will Peyton Manning go?

A lot of speculation has been going around the NFL and sports media the past few weeks about where Indianapolis Colts quarterback Peyton Manning will land his next contract.  The Colts owner, Jim Irsay has money, fan approval and the future of the organization relying almost solely on his decision to either retain or say goodbye to the franchise quarterback.  Manning has been such a huge part of the success the Colts have had for over a decade.  His talent and poise has helped turn mediocre wide receivers into the pro bowlers and even won a Super Bowl.  Despite the recent series of spinal fusion surgeries, Manning has stated he plans on continuing his football career.  Whether he'll be in Indianapolis or not, only time will tell.  For Irsay, there are still some issues that may likely lead to Manning's eventual departure from the Colts.  One is how he recovers from the surgeries and if he'll ever be 100%.  The other worry is his ability to be as efficient and produce the remarkable numbers he's posted in recent years.  For instance, Manning threw for 4700 yards and 33 touchdowns during the 2010 campaign.  As of now, Irsay's biggest concern is Manning's health, which is not a good sign.  Resigning him for another contract would mean spending a ton of money, which may be better invested in players for the future and rebuilding the team.  Whatever the decision may be, the team plans on choosing Manning's successor in April, which will likely come down to Stanford quarterback Andrew Luck or Baylor's Robert Griffin III.
