Great question! They do really need to improve the pass receptions. I lost a lot of assists because of bobbled passes. They even caused me to get credited with turnovers because my cpu teammates couldn't catch the ball. If they were finally able to reign it in, then they were no longer open for the shot. I'm excited to see/feel the passing improvements because that was one of the biggest irritants in 2K13.
Also I would really love to see some more improvements & additions to myplayer/mycareer.
