Michael Vick told a bankruptcy court on Friday that his time in prison allowed him to think about his life, and that he now realizes he needs to make some changes. Vick, who is serving a 23-month prison sentence for bankrolling a dogfighting operation, said he knows he committed a "heinous" act. "I can't live like the old Mike Vick," he told a courtroom. "I was very immature. I did a lot of things I wasn't supposed to do being a role model."
