A new Seattle Seahawks season kicks off this weekend with plenty of intriguing storylines to follow. How the Seahawks deploy their running back tandem of Kenneth Walker III and Zach Charbonnet will be among the most intriguing to watch. Walker, a fourth-year pro in the final year of his rookie deal, brings an electric running style with speed and elusiveness that make him him a home-run threat on each play. Charbonnet, a third-year pro, brings a contrasting style as a punishing downhill runner.
