There's a danger in deciding that once-successful veterans are done for good.
Remember when Kurt Warner played for the Giants in 2004 and was dreadful, fumbling nine times in 10 games? Remember how everyone assumed he was done?
Remember how he then led the Cardinals to the Super Bowl in 2008?
So yes, there is a danger in deciding that a veteran player is toast. That said, I feel confident that the following players should seriously consider hanging it up, because their prospects on the free-agent market will be non-existent.
Thanks for the memories, guys.
