The San Francisco 49ers are offering Norv Turner a lucrative incentive package in his contract in a bid to persuade him to remain and continue developing quarterback Alex Smith, rather than interviewing for the Dallas Cowboys' head-coaching position, according to sources. Seeking a replacement for retired head coach Bill Parcells, Cowboys owner Jerry Jones interviewed San Diego Chargers defensive coordinator Wade Phillips through the morning and into the early afternoon Friday. Phillips also discussed the team's personnel with Parcells, who has also been offering Jones his opinion on the coaching candidates.
