I train WR to speed (min 19 in most cases); strength (min 16), then the following. I like all my starters to have min 10 stamina. With that said, the following skills in order of importance for WR: Catching, agility, footwork, positioning and vision. Under the current game engine, all players use anywhere from 3-5 skills, not counting physicals. This is per the admins. For every position, I have assigned the 5 most important skills, listed them in order of importance and then I simply train them pretty much evenly across those skills. For some positions, I will focus more on the 3 most important skills until they get to a starting position number, then focus on the other 2.
