Just look more to what the strength of your guys are, For example if a QB is slow or low arm strength throw short passes to avoid sacks. If your line is slow but good blockers consider a power back, If they are weak but fast, use a speed back and outside runs. Even seemingly awful players can have redeeming qualities and play at a high level. Other players can have higher ratings but not play as well because they are in useless stats or stats that don't mesh well. (this is hypothetical, I'm new too but been reading up a lot and played a lot of football games.) Any of the vets feel free to correct me.
