SANTA CLARA, Calif. The narrative was that the couldn't come from behind in the Kyle Shanahan era.But during this season's playoffs, they've dispelled that notion with two big-time comeback wins to Cristiano Felicio Jersey advance to the Super Bowl.On Sunday, a major catalyst for San Francisco's over the was the legs of quarterback , who finished with 48 rushing yards."It's just amazing because I don't think too many people know how fast and elusive Brock is until he gets to running," said. "I think I kind of me sed up one of his touchdowns trying to get a lead block, and he ran right into me and bounced off. I feel like if I would have made that block, he probably would have scored."ADVERTISEMENT According to Next Gen Stats, Purdy converted three first downs on scrambles and completed 3-of-4 pa ses for 41 yards and three first downs on pa ses when he scrambled outside the Devon Dotson Jersey pocket.The second-year quarterback said getting outside the pocket and using his legs is nothing new."My job is to distribute the ball to guys that are open," he said. "Then if something is not there, especially in this kind of game, you got to find a way."I feel like throughout my life I've scrambled here and there. Since I've been here, I feel like I haven't done it a whole lot. On Sunday night , I was just trying to keep the chains moving, keep the ball moving forward and then give our team some momentum and some juice."Did Brock Purdy just prove he's a top QB in the NFL? Purdy will never be mistaken for or . The product finished with just 144 rushing yards during the regular season. Of course, when you have explosive runners like and Samuel, it makes more sense to design plays to get them the ball in space."Sick," tight end said when asked about Purdy's scrambling. "Do it more Lauri Markkanen Jersey just don't get hit. Like, maybe tuck the ball a little faster. He scampers I think that's the best way to describe it. You ever seen one of those little water dragons running acro s the water? That's what I envision every time he's running with the football."San Francisco offensive lineman , however, says Purdy is a surprisingly good runner, which adds another dimension to the team's already explosive offense."It's him trusting his legs the more you can do. There's guys like that we're going to Zach LaVine Jersey see. Obviously, , he's a lot slower," McKivitz said with a laugh. "But it gives us another threat and just that extra little thing that the defense has to account for with a guy that can run."While Kyle Shanahan won't be building an inventory of designed runs for his QB, the San Francisco head coach was extremely thankful for the plays Purdy made against the Lions by scrambling."I thought it was the difference between us winning and Jerry Sloan Jersey losing," Shanahan said. "He made some big plays with his legs, getting out of the pocket, moving the chains on some first downs, some explosives."He competed his a s off. Wasn't easy for any of us. He kept grinding and was unbelievable there in the second half."Eric D.
