Agreed. The notion of "breaking out" of a 3 step drop, or even a 5 step drop is somewhat nonsensical. The steps in the drop are pre-programmed in real life, and can't really be altered or the entire timing of the play, not to mention the mechanics of the quarterback, will be all screwed up. You can of course scramble after you hit your last step, but that's entirely different from "breaking out" of your drop. Check those Billick videos LBZ posted from NFL.com, go do that in your back yard, and try to "break out" while you're in the 3rd step of a 5-step drop.
This gets to one of the basic issues in Madden gampeplay, and that's the twitchy and hyper-actuated mobility of the players. It's like the contact between their feet and the ground, as well as the momentum created by that contact, have little to no meaning. If this were to be changed, for example, in the instance of the QB dropback, it would go a long way toward achieving the realism that the crew wants to achieve.
