Now the Patriots haven't won a Super Bowl since 2004, and have also lost two of the last four Super Bowls—both of which happened to be against Tom Coughlin and the New York Giants.
Over the course of the last 10 seasons, Belichick's Patriots have been in five Super Bowls and have won three of them. You certainly can't take that away from him.
Do the two recent Super Bowl losses tarnish Belichick's legacy?
Absolutely not. No way. Not a chance.
Belichick is the modern-day Vince Lombardi. He is the greatest coach of our generation and could very well be the greatest coach in NFL history due to the era that he's coaching in, an era of free agency.
It's certainly not a positive thing losing two out of the last four Super Bowls, but it's a damn good accomplishment to make it that far when 30 other NFL teams are sitting out.
To put this into perspective: Belichick's Patriots have been in the Super Bowl 50 percent of the last 10 years—you can call that domination. That is unheard of.
As we enter the twilight of Belichick's and Tom Brady's careers together with the New England Patriots, some may speculate that their early success simply ran out as they have yet to win a Super Bowl in the last seven seasons.
Belichick has already accomplished greatness, and you cannot take that away from him—even if he has two consecutive Super Bowl losses.
