Where did I mention ice skating or animation related issues? My comments were in specific reference to offensive execution as it relates to 2K12 and 2K13.
Also, are you aware that rosters extend far beyond attributes and stats? I don't know how you would expect to get "REAL-LIFE" gameplay without players having a context for their movements and actions. That context comes from the roster which includes coaching strategy, playbooks, player tendencies, player abilities, player hot spots, player hot zones, player animation packages, and more.
