I like that animation. Just make the throw go somewhere random though.
To the topic: if that new dropback was the standard dropback in Madden, I'd be happy. The way the ball is held by the quarterback in Madden 09 (and all next-gen Maddens, really) is kinda funny.
On the topic of breaking out of the dropback: it should be allowed, but I also think that there needs to be an advantage to using the dropback normally. To bring up an all-too-tired but yet good example, using the predefined pass dropbacks in NFL2K5 and APF2K8, in combination with the routes ran by the receivers in each play, gave the passing game a real sense of rhythm. I don't often get that same sense from Madden (though admittedly there have been a few occasions where I've had that sense occurred in 09, it needs to be more frequent)
Unrelated: I do agree with those above that eventually you all should implement more signature animations, be it dropbacks, tackle-breaking animations, pre-snap routines, etc. etc. if at all possible.
