Chiefs quarterback Alex Smith said Monday he didn't want to go into the season without a contract extension. He won't have to after signing a four-year extension a day earlier.

"I was really hoping that it would get done before [the start of the regular season]," Smith said. "I didn't want to go into the regular season with that. As much as you don't think about those types of things consciously, subconsciously you can't help it. They sit in the back of your head, and you're thinking, 'Oh, I'm playing for a contract,' and this and that. Sometimes it can just be an added distraction. I certainly was hoping and I'm really happy that it did get done."

Smith indicated the delay in reaching a deal was just about finding a number that worked for both sides.

"For me, it was about something fair both ways," he said. "As a quarterback, you certainly don't want to hamstring your team in any way because -- I know this more than anyone -- you rely so heavily on those playmakers around you.
