RENTON, Wash. -- In the second quarter of last Sunday's game vs. the Arizona Cardinals, Geno Smith raised his hands in preparation for the shotgun snap, then stepped towards his offensive line to relay an audible. The new play was a handoff to Zach Charbonnet, who followed two pulling blockers into the second level, broke a tackle and raced 51 yards to the end zone.
The Seattle Seahawks quarterback has considerable freedom to change plays based on what he sees at the line of scrimmage. But this audible came straight from first-year offensive coordinator Ryan Grubb, who had seen Arizona's defensive look from the coaches' booth and correctly anticipated a blitz.
