I think the most succsesful team is probably the Miami Dolphins. They went undefeated and they were super bowel champions that year. This year however the New England Patriots (who I don't like) may top that record if they win the Super Bowl.
Glasgow rangers are the most successful the have won over 110 cups
Joe Montana
Ed Reed
Giants
chicago bears
one of the greatest running backs in NFL history
Some of the worst NFL franchise records in history include the Tampa Bay Buccaneers' 0-14 season in 1976, the Detroit Lions' 0-16 season in 2008, and the Cleveland Browns' 0-16 season in 2017. These are considered some of the lowest points in NFL history for these teams.
Ray Lewis
Danny Cook
because they have won 6 superbowls and consistently have had a great defense.
It is the Detroit Lions with a combined 571 losses since the franchise started in 1930.
JOE MONTANA is the best Quarterback in NFL history. _____________________________________ It depends on your definition of "greatest". If anyone answers this question with one quarterback, they are WRONG. There are too many factors that go into this answer.
The question of who the greatest running back in the history of the NFL could be different for different people. Some people may say Barry Sanders or Walter Payton, but there is no definitive best.
