The New England Patriots, who have outscored opponents by an average of 25.4 points during their 10-0 start, can become the first National Football League team to clinch a playoff berth this weekend. The Patriots opened a five-game lead on Buffalo in the American Football Conference's East Division with their 56-10 win over the Bills two days ago. New England can clinch a sixth postseason berth in seven years with a home win over the Philadelphia Eagles on Nov. 25, the NFL said. The Patriots, who have won three Super Bowl titles in the past six seasons, would also become the first team to wrap up a playoff spot if the Bills lose at Jacksonville.
