Chris Jacke, a laconic individual sometimes labeled as a a selfish player by his friends and colleagues, became a hero Monday night. Jacke's lackluster start to his eighth season in Green Bay turned to jubilation when he kicked a 53-yard field goal 3 minutes 41 seconds into overtime to give the Packers a gripping, 23-20 victory over the game San Francisco 49ers before a record crowd of 60,716 at Lambeau Field. It was the fifth field goal of the night for Jacke, who had missed three of his first 10 field goals plus an extra point in the first six games. All was forgotten, however, when Jacke ended one of the more memorable games of the Ron Wolf-Mike Holmgren era in Green Bay.
