Producer Marcus Stephenson has posted a blog on behalf of the NBA Live Dev Team on EA Sports World requesting feedback on players who like to use the glass; it would seem this is something that will be taken note of in NBA Live 2010 (backboard usage on layups is also mentioned as being addressed). If you'd like to provide feedback check out the blog post
here or feel free to post here in the Wishlist section and I'll be sure to forward along the info.
