‘More than likely, Northern will serve as a backup to Porter, the team’s third-round draft choice in 1999 whose style of play reminds the team of a young Greg Lloyd. Porter had an outstanding training camp and preseason last year, and his development is one of the reasons the team elected not to re-sign free-agent Carlos Emmons, who started the past two seasons at right outside linebacker…Northern is 6 feet 2, 240 pounds and was a starter the past two years in Buffalo. But the Bills did not attempt to re-sign him because Keith Newman, a fourth-round pick in 1999, was expected to be the starter in 2000.’
