The Miami Dolphins confirmed they are the worst team in football this season -- and maybe ever -- by making Buffalo's popgun offense and banged-up defense look spectacular in dropping their 13th straight game. Rookie Trent Edwards' four touchdown passes -- two each to Lee Evans and Robert Royal -- were the most since Drew Bledsoe had that many for Buffalo in 2004, leading Buffalo to a 38-17 win over the woeful Dolphins on Sunday. The Bills' running attack produced two 100-yard rushers for the first time since 1996, with Fred Jackson having 115 and Marshawn Lynch adding 107. Buffalo's defense did its part, racking up a season-high five sacks and forcing four turnovers, including safety George Wilson returning rookie quarterback John Beck's fumble 20 yards for a score. Buffalo (7-6) won for the sixth time in eight games to stay in the AFC playoff hunt while preparing for a key game at Cleveland next weekend.
