The Bills quietly reached an accord with ORG Chris Villarrial, and at a bargain price (four years, $12 million). Villarrial is 31, but he’s a mauler who is rarely beaten or penalized and, along with underachieving ORT Mike Williams, puts Buffalo in position to have the best right side of an offensive line in the NFL. Somewhere, RBs Travis Henry and Willis McGahee are smiling.
