It seems like your individual performance/teammate grade is highly dependant of how good your teammates are. I think I might not even finish the combine. I'm really bored with not knocking down open jumpshots with a shooting guard, trying to get open only to have the center flash to the 3 point line and get in my way, nobody setting me offball screens, can't call plays other then calling for a pick. If I go down to the post to spread the offense when the center flashes up, I get "bad positioning" from the teamwork grade. I play help defense because my teammate gets lost or something, negative grade for leaving my assignment. I'm also pissed that the "how to play" section has crap that you can't even do in the game.
Looking at some of the poor defensive rotation, if any of that is in 2K10, it will be a major problem. This game is severly limited. I don't know how this role playing feature of 2K10 will work out if it's anything like this. I heard the 99 rated players that are getting uploaded will be deleted.
