A source close to Mike Martz tells ESPN's Chris Mortensen that talks between the Detroit Lions and Martz to be the club's offensive coordinator have broken off with the sides unable to reach contract terms. On Wednesday, Martz had accepted the Lions' offer to be their offensive coordinator under new head coach Rod Marinelli, pending the sides reaching agreement on contract terms. The source said Martz was seeking a three-year contract that averaged just under $1.5 million a year. Martz's agent, Bob LaMonte, met with Lions officials Thursday afternoon at the Lions' facility in suburban Detroit before talks broke off. Martz and Marinelli met for several hours on Tuesday but no offer was immediately made to the former Rams coach, who missed the final 11 games of the 2005 season as he recovered from endocarditis, a bacterial infection of a heart valve. The Lions did, though, offer the job to Martz on Tuesday night.
