All recent NFL ties have happened in mid-November and other interesting facts

Since 1989, there have been six ties in the NFL, including Sunday's 24-24 deadlock between the St. Louis Rams and San Francisco 49ers. Here are six facts about the most recent NFL standings oddities.

1. Each of those six ties has taken place in November of various years, over a two-week stretch from Nov. 10 to Nov. 23. That's 15 weeks over each of the past 23 years without any ties and two weeks with six.

2. The longest stretch of games without a tie was from 1989 until the Philadelphia Eagles and Baltimore Ravens tied 10-10 in 1997. Then, after eight years without a tie, it took just seven days for the next one. The Washington Redskins and New York Giants finished deadlocked at 7-7 in the infamous Gus Frerotte head-butt game.

3. There were 10 ties in the 1980s. Those back-to-back ties from the Eagles/Ravens and Redskins/Giants were the only ones of the 90s. The aughts also had just two ties. Sunday's was the first of the new decade. What's the reason for the decrease in tie games? A number of answers would work, but the most logical is that kickers are better now than they were then.

4. No NFL team has won a Super Bowl after tying a regular-season overtime game since the 1974 Pittsburgh Steelers. That team's 35-35 tie against the Denver Broncos came in the second regular-season overtime game in history and still stands as the highest scoring tie game of the modern era.

5. Only eight teams that have been around since 1974 have yet to finish a game tied: Buffalo, Chicago, Dallas, New England, New Orleans, Oakland, San Diego and Tennessee.
