If you are struggling with passes, I suggest you do some of the PA or short passes that have the short out, curls, and flat routes. Those are usually relatively safe and don't necessarily get you the big plays but help to eat the yardage.
Some good plays are Trips TE Quick Slants going to you TE on the out or the curl (curl is more difficult), Bunch PA Pin Deep with the TE running an out, Trips TE PA Deep Attack with the WR1 running a short crossing route (works well against zone, not so much against man), smash with the WR2 or HB (countered a lot), Strong I PA Slide flipped can get the FB in the flat or the TE on the out, Trips TE WR Corner with the TE on the out. She short crossing routes and the outs are the easiest and safest to complete but may not get you huge chunks of yards. If you know how to read the plays, some of these have a different option such as Bunch PA Pin Deep where you can hit the WR1 on a deep route when the DB is behind the WR1 but you have to really know what to look for to do some of the other options. Also, if the receiver you want to hit is covered too tight then either scramble or throw the ball away but you need to be moving out of the pocket and usually in the direction of the receiver you want to throw to.
