By Chuck Pagano and Kevin Baxter,ESPN.comThe last time a major sports team lost a game was at the start of the 1970s.
For a few months, the Chicago Bears were the only NFL team without a winning record.
That was the era of the great defensive dynasty.
Now, the Bears have gone 14-12 since, while the New England Patriots are 8-5 and the Oakland Raiders are 4-7.
The last time the NFL went 0-16 was in the 1950s, when the Oakland A’s were 6-19 and the Baltimore Colts were 4-12.
The NFL is going through the same rough patch.
The Browns are 8.5 games back of the Raiders, who are in the middle of their longest losing streak in franchise history.
The Cleveland Browns are 0-2 after Saturday’s 29-10 loss at Oakland.
The Browns are 6-2 when Tom Brady leads the team in rushing and 4-2 at home.
The Colts are 4.5-1 at home, with their lone loss coming at Pittsburgh on Sunday.
The Patriots and Chargers both are 2-4 at home and are 2½ games back on the Raiders.
The Chargers have been 6-0 in the past six games against the Raiders and Browns, including a 41-35 victory on Oct. 10 in the Chargers’ home opener.
That’s their best start in their last 13 home games, which is tied for the longest winning streak in the NFL.
The Chiefs are 3-0 after a 31-13 victory over the Titans on Sunday night, with the lone loss to be at the hands of the New York Jets.
The Chiefs are 5-1 in their past six road games and 4½ games ahead of the Chargers.
The Bengals are 2.5 backs away from winning their first playoff game since the 2010 season.
The team is 2½ backs away after dropping a 17-10 decision to the Tennessee Titans on Monday night.
The Bills are 6.5 back of Atlanta for the second wild card in the NFC East.
The Eagles and Saints are tied at 7.
The Bucs are 5.5 behind the Saints for the eighth and final wild card.
The Jets are 6½ games behind the Cardinals for the division lead.
The Cardinals have played seven games, and they’ve been 4-0.
The Jets are 3½ games away from clinching the division, but they’ve lost three straight.
The Falcons are 5½ games out of the final wild-card spot, but there is a slim chance they can get to 7½.
The Eagles and Packers are tied for first in the AFC South, and the Colts and Titans are tied with a combined 2½-game lead.
