Less than a week remains until the Seattle Seahawks begin the defense of their Super Bowl title.Seattle will kick off the NFL season on Sept. 9 with a Super Bowl rematch against the New England Patriots. The Seahawks’ roster looks quite similar to last season’s, aside from additions like edge rusher Dante Fowler Jr., rookie running back Jadarian Price and wide receiver Montorie Foster Jr., who stood out in training camp.Without further ado, let’s get into some questions for yours truly’s first mailbag as a Seahawks beat writer. Questions are lightly edited for brevity and clarity.Seahawks thrilled to have Leonard Williams locked up for years to comeAndrew DestinHow would you explain the decision to not have a true three-down RB1, and the platoon approach after drafting Jadarian Price? Do you think the team might end up regretting letting K9 walk more than any other free agent? — Michal P. The Seahawks would have loved to retain Kenneth Walker III, especially considering that his complement last season, Zach Charbonnet, will miss at least the first four regular-season games on the physically unable to perform list as he works his way back from a January ACL tear.But general manager John Schneider was wise not to give the Super Bowl MVP a three-year deal worth up to $45 million, including $28.7 million guaranteed, as the Kansas City Chiefs did.That said, Price was not drafted as a direct replacement for Walker, nor should he be a Charbonnet replacement as the latter nurses back to health.Price was slowed by “upper-leg soreness” early in training camp, making it that much easier for the Seahawks to embrace a platoon. I anticipate Price will be featured plenty on first and second downs, while third-year pro George Holani will be used on third downs, short-yardage situations and around the goal line.Certainly, the duo of Price and Holani — with free-agent signee Emanuel Wilson occasionally mixing in — does not look as strong on paper as Walker and Charbonnet. Whenever Charbonnet returns, though, he will pair well with Price, which should allow Holani to slide back into a third-string role.If the Seahawks can manage with Price and Holani the first few weeks of the season, they will be just fine in the long run and not miss Walker.What does a realistic season look like out of Jadarian Price? — Ryan T. There are so many factors that must be considered when answering this question:
