Initially, Todd Gurley did not understand what all the fuss was about. The Rams running back was a rookie in 2015 when he scored a fourth-quarter touchdown against the Seattle Seahawks in a December game at CenturyLink Field. In celebration, Gurley spiked the ball. But a Rams player told him he should have made it a keepsake. "My teammate was like, 'Boy, what you doing? You better keep that ball. You know how many people score in Seattle? Nobody,' " Gurley recalled this week, laughing. Gurley's touchdown propelled the Rams to a surprising victory over a team that has featured one of the NFL's best defenses for more than a half-decade. The Seahawks' defense was fully stocked in last season's victory over the Rams in Seattle, and this season in a 16-10 victory over the Rams in Week 5 at the Coliseum. But Sunday, Gurley and the Rams will go against an injury-riddled Seattle defense that will be without star cornerback Richard Sherman and safety Kam Chancellor, among others. Linebacker K.J. Wright is doubtful and linebacker Bobby Wagner is questionable.
