Rich Gannon says 49ers quarterback Alex Smith needs to show more fire on the field as he looks to turn his career around. Gannon, a former Raiders quarterback, will call Sunday's game between Oakland and San Francisco. "I just think that to play this position and to play it well, you have to have a little bit of a jerk in you," Gannon said. "And I say that constructively. If you look at Tom Brady, if you look at Peyton Manning, if you look at Drew Brees, if you look at Brett Favre ? I could keep going on and on. All these guys, at the end of the day, if they have to take out that whip and let you feel it across the back of your legs, you're going to feel it."
