The Dolphins have signed David Garrard to a one-year contract. Garrard, a former starting quarterback for the Jaguars, has been told that he will be given a shot to win the team's starting job. Miami failed to sign Peyton Manning and Matt Flynn. They also hosted Alex Smith for a visit Sunday and may still consider signing him. "They didn't say for sure they were bringing another guy in, but they said it's a possibility, whether in the draft or whatever," Garrard said.
