RIVER FALLS, Wis. -- Some Chiefs fans have gotten nervous about new quarterback Matt Cassel because he struggled in a scrimmage and was not overly impressive in Kansas City's preseason opener.
Kansas City coach Todd Haley, however, is not concerned. In fact, he has been quite impressed with the quarterback, whom the Chiefs traded for this offseason.
"He has a chance to be special," Haley said.
Haley came to Kansas City from Arizona where he was the offensive coordinator. He was always impressed by the work ethic of Cardinals quarterback Kurt Warner. Cassel reminds Haley of Warner.
'They're very similar in the way they approach the game," Haley said. "Football is all Matt thinks about, just like Kurt. He's thinks about it all the time. He texts me about the game all the time. It's just who he is. He's very serious about this .... He's going to be very good."
