Bobbie Williams (Cincinnati): The Ravens know all about Williams, having gone up against the former Bengal the past eight seasons. Williams is huge (6-4, 345 pounds) and he's long been considered a pretty good run blocker. However, there are a lot of question marks with him as well, and there has even been some speculation that he could retire. He's 36 years old and he played in only nine games last year. He was suspended for four games for violating the league's policy against performance-enhancing substances, and then he sustained a broken ankle in early December. He'd certainly be a short-term solution.
