Bills LB Barnett making immediate impact

It hasn't taken Buffalo Bills linebacker Nick Barnett long to show he hasn't lost a step. Dispensable in Green Bay after injuries caught up to him, Barnett has helped his new team to a 4-1 start. Any lingering questions of the nine-year veteran being over the hill were put aside in a 31-24 win over the Philadelphia Eagles last weekend. Barnett returned an interception for a touchdown, and then had a second one to end the Eagles' final drive. Not bad for a player who opened the week wearing a protective boot on his right ankle. Barnett's not surprised, and says he's yet to have played his best game, as Buffalo prepares to play at the New York Giants (3-2) on Sunday.
