Need just Passing tips in general

So I use the Steelers mostly. I really struggle to pass the ball. The only stuff that seems to work for me are crossing routes over the middle. Any just general help?

When i go with the passing game i like to work in some passes to flats and throwing to some corner routes. Outs work well for the short gainers unless you can break into the open. What i think is most important is when your playing online use Willie Parker to start off and work in a few passes. Make your oppent fear your running game and if you can do that successfully they may play a 4-3 defense which should allow to free up the passing lanes. Everyonce in a while try some deep passes to keep the defense back if they start playing a flat zone. That should work for ya.
