Your first and second paragraphs way of thinking is the "problem" for the lack of a better word.
First paragraph
Let's look at this from a different point of view. Let's not even mention the other company whatsoever. Let's simply compare Live's animation to real life NBA and athletic player movements. One should be able to sample EA Live's player movements and make a direct visual comparison to real basketball player movement and see a pretty significant concern, and how it's not quite ready for primetime.
There are three popular online animation schools (animation mentor, ianimate, animschool). There are large animation studios, such as Pixar and Dreamworks. Submit NBA live footage and real NBA footage to any of these companies and they will be able to pinpoint exactly what the problems are, and what changes needs to be implemented to get more realistic fluid life like movements. Even if EA submits it to students and professors at any accredit animation art school and they'll see a reason for concern.
Bottom line: I was hoping for animations that truly capture the essence (i.e. smoother, more realistic animation) of a real athlete on the court.
Second paragraph
It's a current preference because you've never experienced a sport game that offers both realistic smooth animation and total player control. Let's look at two baseball games as examples: MLB the Show and Pro Yakyuu Spirits.
Fans of MLB the Show love the game and its animations, however, sometimes one may lose control of their players causing frustrations. Pro Yakyuu Spirits (PYS) combines the best of both worlds, way better animations and PYS offers absolutely full player control.
Bottom line: Player control doesn't mean one has to sacrifice smooth realistic animations.
My first reaction was that looks kind of like Tyson Chandler.
