depends on the type of Qb you are trying to build,
Gunslinger, strength heavy (Me, just because i havent seen anyone suggest strength as much as I have)
Game manager, vision heavy (jeff garcia, many others love it, jeff is probably best with it)
Balanced Qb would probably be (Ilok)
It is probably best to use the QB guide at top. Tons of time and effort went into it and it gives you a pretty good idea of how to make a successful QB
