GLENDALE, Ariz. -- Geno Smith looked at his teammates on the Seattle Seahawks' sideline and tapped his chest, signaling to them that the Arizona Cardinals' go-ahead touchdown was on him. Not that there was any question. Smith's screen pass intended for Kenneth Walker III had just ended in disaster when it was tipped and picked by linebacker Zaven Collins, who returned it 30 yards to the end zone to put Arizona up 14-10 midway through the third quarter.
The worst mistake of Smith's brilliant season could have doomed Seattle on Sunday at State Farm Stadium.
