The Comp pass has come out today, and their are a lot of great rewards including 89 George Pickens, 86 AJ Terrell, and 2 87 Legends.
The first step you're going to want to do, is playing on rookie mode in solo battles. This makes it very easy to get the stats done, by throwing up streak routes, and just running the ball for rushing stats. You will also rack up points and wins for solo battles.
For the mut champs and h2h seasons, you can play those games at a normal, fun pace, and not be a tryhard unless you're good and get 16+ wins. If you're like me, and get 10-12, I wouldn't really play those games that often.
Hope this was informative to the newer MUT players.
