Defensive tackle Pat Williams said Monday that he's "50-50" on whether he will return for the final year of his contract. At 37, Williams is the second-oldest player on the team behind the 40-year-old Favre.
"I feel good [physically]," Williams told the Minneapolis Star Tribune. "But yesterday was tough on me. It was draining. You do all that work during the season, so you just feel drained."
Williams said he talked about the situation with Favre, who has famously struggled with whether to retire for the last few years.
"It would be kind of tough," Williams said, "but I see how Brett [Favre] felt. Basically, like he said, you go through a season like that and you're drained. I feel like he feels. When he was in Green Bay, he lost the NFC Championship [in 2007] and felt like he was drained. But he still felt like he had to come back and prove something."
Favre told him, "It's all your choice. It's all going to be on how you feel and then how you come to [a decision]."
"I do it because I have fun," Williams added, according to the Star Tribune. "I don't do it for anything else, so if I ain't having fun, I'm not going to do it. I always have fun being around these guys. I like coming to work every day, laughing with these guys. So if I don't feel like I'm going to have fun, I ain't going to do it."
Williams was the anchor of a Vikings defense that gave up the fewest rushing yards in the NFL for three consecutive seasons, starting in 2006.
