Perfect Patriots face Bills test ahead of Brady return (AFP)

New England Patriots coach Bill Belichick will attempt to extend his dominant reign over Buffalo Bills rival Rex Ryan on Sunday as the AFC giants aim to maintain their perfect start to the season. Belichick’s rivalry with his outspoken Bills counterpart stretches back several years, from when the pugnacious Ryan was head coach at the New York Jets. To date, Belichick has rarely been troubled by anything Ryan has thrown at his teams, with the Patriots coach leading 9-1 in their last 10 meetings.
