The Dolphins reached into their own past be re-signing TE Eric Green, who last played for the team in 1995, and last played in the NFL in 1999.
As we hear it, he was quoted as saying "I'm happy to be back in Miami, but I was wondering where Don Shula is these days?"
After a few hours, the Dolphins realized their mistake, and contacted the current Eric Green, a db who last played in Arizona last season. They offered him a contract and told the other Green "oops!" A team spokesman said "you can understand our confusion, because the guys both have the same name. But we thank the elder Eric for understanding, and he's welcome to come in for a tryout."
