WR Double Pass.
This play works well against man and zone. However, if in Man, you will have to forget the pass to the WR#1 and look elsewhere, the backside RB is almost always open.
If in Zone this play works very well, especially if you throw back across field to Beanie Wells going up the opposite sideline. Trying to throw to the other receivers is hit or miss, because Fitzgerald doesn't throw the ball well at all, but across the field to the RB is almost always on target.
Gun (spread, i think) there are motion plays that has Boldin motion across the formation behind the QB. All three plays that use this motion work really well.
Flea Flicker. If you can get the return flip from the running back, which isnt easy because he often gets stuffed, you usually have breaston free.
Pahokee option with Beanie Wells works pretty well for short yardage plays, thanks to his trucking. Or if you can sub breaston into the QB spot, he works better than fitz or boldin, as he is faster.
With this team, whomever is in the Slot is your best option. Usually it's Breaston. Other teams you have to sub your #1 reciever into the slot to get matchups on the LB's, but with the Cardinals, breaston is already there and is the fastest WR on the roster. Most people key of Fitgerald, and Breaston is your best threat.
