Jones agreed to a four-year deal worth around $3 million a year. The contract is similar to the five-year, $14 million contract reached with halfback T.J. Duckett earlier this week.
With Jones and Duckett on Seattle's roster entering the season, the question is whether or not Shaun Alexander will be around. The Seahawks decided to keep Alexander until they found replacements and now they have two potential replacements.
Jones is expected to compete for the starting job. Duckett was signed to be a short-yardage back as well as a backup fullback and power back. Jones is considered a more elusive back than Duckett.
