Adjust the sliders to your advantage (max out the user sliders and decrease the computer AI sliders).
I did this one on my way to the 35 point achievement. Just get the ball on offense and get to the end zone four times through the air. Once the sliders are in your favor, this should be extremely easy.
You can combine this with several other achievements (30 yard pass, 60 yard pass, 35 points, win by 21).
