In Create A Fighter mode, preview a fighter. Toggle his stats on, then off. Select him and choose the "Customize Attributes" option. You will have 3024 points to distribute. Distribute all the points, then select "Finished". Once the game saves, go back to Create-A-Fighter mode, and repeat the process until every skill is at 100. Note: This only works for fighter skills; Cardio, Speed, and Strength attributes are not affected by this glitch. This trick does not work in Career mode.
