The Seattle Seahawks offense will face a stiff Atlanta Falcons defense on Sunday in Week 14. Klint Kubiak’s unit had to achieve precious little last week to enjoy a 26-0 shutout victory over the Minnesota Vikings. Sam Darnold and Co. might need to be more productive on Sunday.We’ve identified three potential X-factors for the Seahawks on offense in Week 14.Sam Darnold, QBDarnold completed 14-of-26 passing attempts versus the Vikings for 128 yards and zero touchdowns. He fumbled twice, losing one. Darnold and the offense rode a strong defensive performance to victory. Though Seattle’s defense may repeat that effort versus another backup quarterback, the offense needs to be considerably more productive.Jaxon Smith-Njigba, WRIt was also a peculiarly quiet game for Jaxon Smith-Njigba the last time out. The NFL’s leading wide receiver recorded just two receptions for 23 yards. Kubiak will undoubtedly want to get JSN back on his record-breaking track despite drawing a tough matchup versus A.J. Terrell and the Falcons’ well-coached secondary.Charles Cross, LTThe Falcons defense ranks third in sacks with 43.0 takedowns. Darnold was sacked on four occasions last weekend. The Falcons have a pair of productive pass rushers in Jalon Walker and James Pearce Jr. Left tackle Charles Cross will need to play a technically refined game.This article originally appeared on Seahawks Wire: Seahawks vs. Falcons: 3 X-factors on offense for Week 14
