When playing wide receiver in Coverage Challenge in mini games, hold sprint and sprint backwards until you reach the barrier.
Keep on sprinting into the barrier until the defender is next to you.
When the defender is next to you sprint toward the endzone.
You should be able to easily burn the defender by 3 or 4 feet.
When you call for the ball or when the quarterback automatically throws the ball to the wide receiver, you should be able to catch the ball and go straight into the endzone.

Tip: Pick a team with a fast wide receiver
