Goto http://nbalive.org for the patch and the previews.
I updated all the maximum detail player models and the jersey neck types. The changes made to the player models include longer & narrower shorts for the "long" shorts type, narrower shorts for the "short" shorts type, slightly smaller shoes, tweaked muscles, lowered & thinner waists, and a less-tucked in jersey. The individual player-specific models (which include Shaq, Yao, Shawn Bradley, Rodney Rogers, Baron Davis,Ben Wallace, & Karl Malone) have the same changes as the general player models, but have also been tweaked to look more like the individual player.
I tried to make the players look more realistic. If you like it, download it. If you don't, don't use it. BTW, the previews only show a few of the different bodytypes and jersey neck types.
