Idk bro, i just completed my 5th powerline master today. Im 5 for 5 on the last event too. Its hard but u just gotta find the right plays. I use a smash mouth coach
Best way to complete this event is to run the ball for first downs very slowly. Let all the time run down as far as you can between each play. All you need to do is get into field goal range and keep the ball. You really only need about 5 first downs to accomplish this. When time is almost gone kick a field goal. They never get the ball. Easy peasy
