playbooks

This may seem like a silly question, im not sure.
Im pretty new hence the question.
I look through the playbooks and to me i see basically the same plays in each book.
Are any of the playbooks better to use and what are the main differences.
Also i first got into madden on my psp with madden 08. In this game you could throw the ball to the half back or the receiver who could then throw the ball. These plays dont appear to be available in madden 09.
I play the ps3.

yea its way more advanced..my biggest advice would be to go to the practice room, or find an lab partner to experiment with.. because on this GAME, timing is jus about everything..

Most used book I BELIEVE are Run And Gun, Tampa Bay, Pittsburg, New England, maybe Indianapolis. I'm sure theres few more but those are the ones I have used.
