The veteran running back, re-signed by the New York Giants on Tuesday, had just five carries for 7 yards in a season with the San Francisco 49ers he called a "curse." He was suspended three games for posting negative comments about the team on Instagram before being released before the start of the postseason.
The timing of Jacobs' Dec. 31 release precluded him from joining another team for the balance of the 2012 season.
"I didn't think I was done because they didn't want to release me," Jacobs said Wednesday, according to the team's official website. "I was told point-blank, 'Do I look like a fool? I release you and you'll be with somebody else and come back and play against us?' I felt good about it. I'm like, 'I see, y'all are scared of me. It's cool. I'm all right.' "
Jacobs added that he can be as "productive as any running back in the NFL," so it's important to take what he says with a grain of salt.
