‘It’s hard to improve on being the top-ranked defense in the NFL, which the Bills were in 1999. But there is one area the team is looking to get better. Despite their defensive success, the Bills did not create a lot of turnovers. They forced 21 of them last season, the 15th-lowest total in the AFC and 29th overall in the NFL. But if the preseason is any indication, the Bills may wreak more havoc on opposing offenses than they did a year ago. In four exhibition games, the Bills created 10 turnovers (four interceptions and six fumbles). There were at least four other passes that could have been intercepted and a couple of forced fumbles that were almost recovered. "The more opportunities you give your offense to score, the higher their scoring percentage is going to be," linebacker Sam Rogers said. "This defense has that capability to make things happen. It’s an exciting defense to play in."’
