Mario Williams, the top draft pick in the 2006 NFL draft, spent his first day and night as a free agent in Buffalo visiting the Bills. Buffalo GM Buddy Nix, along with defensive coordinator Dave Wannstedt, flew to pick up Williams and bring him to Buffalo. The Bills are prepared to make Williams a mega offer, but reports late on Tuesday said that Williams will not sign with the Bills right away and plans on making at least one more visit to another NFL team
