Marcus Vick and the Miami Dolphins

Vick declared his eligibility for the NFL draft on January 7, 2006. After the 2006 NFL Draft, he told ESPN's Michael Smith that he considered himself a better quarterback than Matt Leinart, Jay Cutler, and his brother Michael Vick.

Despite pre-draft speculation that Vick could go as high as the third round, he went undrafted, becoming an unrestricted free agent who could sign a contract with any team. Many of the NFL's scouts questioned his attitude and his ability to avoid future troubles on and off the field. Vick attended a Miami Dolphins rookie free agent minicamp after the draft, and was subsequently signed to a free agent contract as a "wide receiver/quarterback/return specialist", for league minimum pay, by the Dolphins.

He was released on September 2, 2006 to reach the Dolphins' regular-season roster limit, but was re-signed to the practice squad on September 4. His number was 16. On October 17, 2006 the Miami Dolphins signed him as a Wide Receiver/Kick Returner/Quarterback. He was signed from the practice squad to the active roster for the team's Week 7 game versus the Green Bay Packers. He was listed as the No. 3 "emergency" quarterback on the depth chart. His first action in the NFL was a regular season game against the New York Jets on December 25, 2006. He played the wide receiver position for the 4th quarter, but had no recorded receptions. After the season, his contract expired, and the Dolphins opted not to resign him.
