Vikings defensive tackle Pat Williams, who will be a free agent once the NFL lockout ends, puts his chances of returning to the team at 50-50, according to The Star Tribune. Williams, 38, said he talked to Vikings coach Leslie Frazier last month during the short time that the lockout was lifted and he received assurances that the team wants him to return. Williams previously said he didn't trust the Vikings, with whom he has spent six seasons after eight years with the Bills. "It's just guys up in the office, man," Williams said. "You know how the front office is. It's just certain guys up in the office. I don't have a problem with Coach Frazier. Me and Coach Frazier talked. We talked a lot of times. It's just people up in the office, man. With a lockout going on now, it's all the same. Business."
