Peterson feared Williams could be adversely affected by the NFL's offseason lockout. "He saved my career because, I mean, you don't know what you've got to train for," Williams said Wednesday in an exclusive interview with this news organization. Williams, 37, is midway through his 16th year in the NFL. He's heading for his fourth and perhaps final playoff push since coming to the 49ers in 2020. Sunday will mark only his second-ever game in Houston, his offseason home.
