I don't know how old you are, but for a Boston sports fan to put this time above the 1956-69 Boston Celtics is amazing. I love the Patriots, and yes this team is incredible. Have been a fan since the team was formed in 1960 and this is indeed the best era we have ever seen and likely will see. And no doubt the best in the NFL considering the whole body of work over the past 12 seasons.
BUT the Celtics won 11 championships in 13 years. Stop and think about that and let it sink in. 11 championships - almost twice as many as Michael Jordan's bulls, more than half the team's overall total of 18, were won in just 13 years. And 8 of those were in a row. From 1959 through 1966, the Celtics won 8 championships in a row. These Patriots are great, and they are doing it in an era of salary caps and free agency which somewhat changes the equation, but they still aren't the best team in the history of sports. No way, no how.
