"It is a challenge, quite honestly," Pederson said. "I had an opportunity when I was in Green Bay to do this back-to-back, two Super Bowls back-to-back. Historically, you watch teams that have had success and gone back. The Patriots have probably been the team that have been the most consistent at it. That's the thing you guard against. You guard against so-called burnout or the energy level is down. You also have to guard against what success looks like to everybody and how that can pull on people and distract people. Players, coaches, I'm included."
