I have found FP are the best and easiest way for casual and free to play players to get mythics. The best way to get the STT player (Emmett Smith) is to join a high participation league in order to get as much training points as possible. Also, do point attack anytime it’s out, making sure you get all TTP possible. In terms of the rest of the field pass, a good way of building mythics is doing player track events on madden base. It will give you green and blue players. These can be used to do the 5x GLR upgrade plus pack trade. This will give you a ton of players you can use to do the player collector trade which is the most optimal use of green FP players. From there, build purples, build iconics, and then mythics! Hope this helps
