The Kansas City Chiefs' offense ranks a middle-of-the-pack 18th in the league according to and Alex Smith is 20th in QB efficiency. The 2005 first-overall pick who spent the first eight years of his career in San Francisco is also completing just 56.5 percent of his passes (his lowest conversion rate since 2007). But the Chiefs are 6-0 tied for first in the AFC West with the Broncos and easily the biggest surprise of this young season. Coach Andy Reid credits much of that success to Smith's ability to oversee the offense. “Listen he's taking care of the football and when it counts he makes the plays. I appreciate that” Reid said. “We're winning football games and he's doing a nice job of managing it and everyone feeds off it both sides of the ball his ability to manage it.” So what you're saying Andy is that Smith is -- what's the word -- a game manager? That was rhetorical because that's exactly what Smith has been this season and we mean that in the most laudatory sense. New defensive coordinator Bob Sutton has taken virtually the same players and turned the Chiefs' D into the league's best unit. That means that Smith doesn't need to win games with his arm but just … well manage not to lose them. And he's been brilliant in that role. “Alex has a big arm he controls the offense and he makes plays when he has to” wide receiver Dwayne Bowe said. “If I'm taking two people he's going to get the check-down. We're going to play conservative. We're not going to make mistakes.” The Chiefs face the Texans this week and Houston coach Gary Kubiak has been impressed by Smith thus far.
