NFL: CHICAGO (1-3) at GREEN BAY (4-0) <h3>Packers seek 5-0 start against reeling Bears</h3> Chicago (1-3) at Green Bay (4-0) Sunday 8:15 pm EDT GREEN BAY, Wisconsin (Ticker) -- With their fans basking in theglow of Brett Favre's accomplishments, the Green Bay Packers nowhave a chance to accomplish something thay have not done sincethe days of Vince Lombardi. The Packers seek their first 5-0 start in more than 40 years onSunday when they host the Chicago Bears in an NFC North battle. Green Bay has not opened a season with five straight victoriessince 1965, when the Lombardi-led Packers won the first of threestraight NFL championships. Green Bay also has a chance to all but bury one of their biggestrivals. A victory Sunday will give the Packers a four-game leadover the Bears. But recent history shows that the Bears can recover from theirslow start. They also opened 1-3 in 2005 and rebounded to finish11-5. Last week, Favre broke Dan Marino's NFL record of 420 touchdownpasses as the Packers defeated another division foe, theMinnesota Vikings. The 23-16 victory gave Green Bay its first4-0 start since 1998. The 37-year-old Favre is playing like the Favre of 10 years ago,completing completed 32-of-45 passes for 344 yards against theVikings. He threw two TDs, raising his career total to 422. Favre has cut down on his interceptions, tossing only two inGreen Bay's first four games. In the last two years, he threw47, including a league-high 29 in 2005. The real question for the Packers, however, is if they cancontinue to win without an effective running game. Green Bayranks last in the NFL in rushing. "Our run game at this point is non-existent," Favre admitted. "Idon't think we can win consistently unless we get morebalanced." The reeling Bears will look to bounce back after surrendering anNFL-record 34 points in the fourth quarter of last week's 37-27loss to the Detroit Lions. They led, 13-3, after the third quarter. Brian Griese replaced Rex Grossman, who was benched, andcompleted 34-of-52 for 286 yards and two TDs. But Griese alsothrew three interceptions. Chicago coach Lovie Smith gave no indication that he would goback to Grossman this weekend.
