It wasn't enough for the 49ers against the Seahawks. They had to dig out some of the old plays too.With Robert Griffin III Jersey the first quarter winding down, quarterback Brock Purdy lined up with Christian McCaffrey and Ray-Ray McCleod III in the backfield. He first faked to motion man McCleod and then swung around and faked to McCaffrey, getting the Seahawks' defense on skates.Purdy then hit a wide-open tight end George Kittle over the Morgan Cox Jersey middle for the fist touchdown of the game.The double fake from Purdy! Kittle is in for the TD on Prime VideoAlso available on NFL+ NFL (@NFL) The play went for 28 yards, and no one came close to bringing Kittle down.MORE:NFL fans were enamored with the call from Kyle Shanahan.This is one of the coldest play designs of the season. Shanahan is out for blood tonight. TheOGfantasyfootball (@TheOGfantasy) Ok that Tony Jefferson Jersey play was sickBrock Purdy THRIVING in the Kyle Shanahan system Big Game Bengal (@BengalYouTube) Kyle Shanahan in his bag is so fun. John Ford (@fordtough301) This is so evil BUM CHILLUPS AKA SPENCER HALL (@edsbs) It's no secret that good coaches steal plays, but Shanahan took a page from one of the most revered names in Nico Siragusa Jersey 49ers history. On a night they were wearing Steve Young's throwback threads, the Niners also stole a play Bill Walsh drew up, as noted by Ro s Tucker.Kyle got Kittle TD play from Bill Walsh. So cool. Ro s Tucker (@Ro sTuckerNFL) This type of play has, of course, been run since Walsh and Young ran the Falcons' defense off the field in the above highlight. Andrew Whitworth called it a "Shanahan favorite" during the "Thursday Night Football" halftime show. But seeing it run in these jerseys, in Brandon Carr Jersey this matchup, with these stakes the Niners can clinch the NFC West with a win Thursday night is special.
