FILE - In this Aug. 7, 2012, file photo, Miami Dolphins head coach Joe Philbin, center, talks to linebacker Karlos Dansby, right, as linebacker Cameron Wake, left, smiles during a stretching exercise at NFL football training camp in Davie, Fla. For the first time since the 1960s, the Dolphins (No. 27 in the AP Pro32) have endured three consecutive losing seasons, and the team is hoping that the consistently strong defense can lead an inexperienced offense to a different result this year. The Dolphins are scheduled to begin their regular season on Sept. 9 at the Houston Texans. (AP Photo/Alan Diaz, File)
