How much of an advantage do some teams in the league have schematically over others?

"I am a big believer that coaching plays a significant role in wins and losses in the NFL. Talent-wise, teams are not that different. Outside of the quarterback position, it very often comes down to coaching, which is primarily playing to your strengths and minimizing your limitations. Some organizations are better than others at utilizing their players and really diagnosing what makes the other team successful. Bill Belichick is really good at that. He has a great feel for the strengths of his own players and taking away the one or two things that the other team does well."
