Play as Atlanta. The return man #21 is super fast and can evade tackles with his speed. Set up a preseason game against New England. Either let the other team score so they then kickoff to you, or win the coin toss in the beginning and try to return in on the first kickoff. The opposing players sort of "lock-on" to you, so try to lead them into your team's blockers. If you can make it past the initial line of players, they will be playing check up to you, and they will catch up. Run in a zig-zag pattern to evade their tackles.
Follow the method in this video:
If you lose the coin toss in the beginning you could always quit and start again to guarantee you start as the return team or if you fail in your return attempt.
