Premise: With a 38-35 victory over the New York Giants at Giants Stadium Saturday night, the New England Patriots became the second team in the modern era of the National Football League to go undefeated (16-0) in the regular season. The only other team to have achieved this feat was the Miami Dolphins in 1972, who were 14-0 due to a different regular season structure at the time.
Hypothesis: There are 31 teams in the NFL.
