By the time the NFL season rolls around many things can change for teams like cuts, injuries, etc...However I think it is important for you to look at the schedules ahead of time and see where teams may have letdowns...the best one is the division sandwich...simply put a team will play another team out of division in between two divisional games...for example look at the AFC EastBuffalo plays at home against Miami, and the Jets before traveling all the way to Oakland to play the Raiders and then.
