Welcome to the board twisted...
The Prima Official Strategy Guide for both NCAA and Madden are pretty deep and decent. They do well as far as discussing plays and packages. I recommend that one for sure, although they cost roughly $15.
Also, if you go to
www.gamefaqs.com they have some strategy guides there created by normal people. You can even find the complete rosters for NCAA there!
I hope that works. Good luck and let us know how you progress!
